Update: HOI 4 – Historical Infantry Division Layouts – Early War #Hearts of Iron

Original video & script: HOI 4 – Historical Infantry Division Layouts – Early War #Hearts of Iron

Intro

Since my first historical division layout video was a major success and a lot of people asked for more, I will do more, but first I have to address the errors in my original layouts, so here is a short update were I discuss the errors, some community contributions and of course the updated layouts briefly.

Thank you

First, thank you all for the great feedback, especially on the paradox forums. Now, there are two people I want to mention explicitly:
First, the steam user ramadawn, who created a mod with various historical divisions, which is also available on the steam workshop.
Second, the paradox user elfiwolfe for giving a lot of good feedback and creating a wiki page with divisions that are derived from my layouts with additional ingame values.
In both cases I didn’t have time to check them out thoroughly, but from their conduct, comments and the data I looked at, I have a good initial impression.

Errors in my first video

Now, when I did my first video I missed a few things that lead to several errors, most notably:
1) Initially, I wasn’t sure if the Artillery Battalions ingame were actually artillery regiments or not.
2) I missed that the support units have less equipment and guns than their equivalent regular combat units.
3) I assigned far too small numbers of anti-tank units in the original video.
The first part, the ingame artillery battalions are actually 3 historical artillery battalions, additionally the game files calls them artillery brigade. Whereas a historical artillery battalion had 12 guns the ingame has 36. For this reason the number of artillery units in my original videos were way too high.
Second, I missed that the number of guns in the support units for anti-tank, artillery, and anti-aircraft is less than that of the regular combat battalions. Basically, a regular combat unit has 50 % more guns than the support version. This allows a bit more fine-tuning, but also note that the support units have special characteristics ingame that I won’t cover here.

Third, in my original video I was far too strict on the anti-tank units. For some reason I neglected the ingame number of guns and used the German Infantry division as reference, whereas in this video I will set the ingame numbers in direct reference to the historical numbers.

The Changes

Since I covered the historical division setups in the original video, I will not narrate the whole setup again, so if you are interested in the background and haven’t see the original video you might want to check it out beforehand, it is mostly military history.

Note that these units are optimized historical accuracy and not gameplay.

German Infantry Division 1940

So, let’s get started, the adapted setup for the German Infantry Division from 1940is as follows:
Due to the high number of more than 70 anti-tank guns, I recommend to use 2 regular anti-tank battalions and remove the support anti-tank gun unit. The number of artillery battalions should be reduced from 4 to 1, since the ingame artillery battalion are three times the size of historical ones.

Now, since the historical unit had 48 artillery guns, an alternative setup would be to use no regular artillery unit, but two support artillery units, this would give the correct amount of artillery pieces for this unit.

german_infantry_division_1940_hoi4_v1_1

Soviet Rifle Division 1941

Since, we covered fifty shades of grey, time to take a look at Big Red, well no that is too scary, so let’s go with the Soviet Rifle Division from April 1941 instead.
Based on the data, I propose the following changes:
Reduce the number of artillery battalions to 1 or 2 units. Since, the division had 54 anti-tank guns and my original proposal had a regular anti-tank battalion included, one could add an additional support anti-tank unit. This would bring up the total ingame number of 60 guns, which slightly above that of the historical numbers.

US Army Infantry Division 1943

Yeah, well, the Fourth of July is over, but freedom never ends, so next is the US Army Infantry division layout from July 1943.
The changes are very similar to the German and Soviet unit. Reduction of the artillery units to just 1 artillery battalion. Then adding a regular anti-tank unit and also an optional support anti-tank unit, since the historical division had a total of 57 anti-tank guns, thus just being short 3 guns to be on point. Also similar to the German division, it had 48 artillery guns, so an alternative setup could be no regular artillery unit, but two support artillery units, to get the same amount of artillery pieces as the original division layout.

British Infantry Division 1939

Now, if you like to call things Spandau, here we go, the British Infantry Division in 1939 of the British Expeditionary Force.

The changed layout for the British is as follows:
I would add an anti-tank battalion and maybe an anti-tank support unit, although the real division had only 48 anti-tank guns, it had a large amount of anti-tank rifles. Also only one artillery battalion. The rest stays the same.

Japanese Infantry Division 1940 Standard B

Now the war situation may still not necessarily develop to your advantage, nevertheless here is the update for the Japanese Infantry division Standard B around 1940.
The changed layout for the Rising Sun is as follows:
No regular artillery battalion, because of the very limited amount of firepower provided by the Japanese. At most one artillery support unit should be added.
(Source: Rottmann, Gordon: Japanese Army in World War II – Conquest of the Pacific 1941-1942)

Italian Infantry Division 1940

In case you want to go full duce, here is the changed layout for one of the most dangerous pizza delivery services in history, the Italian Infantry division from 1940:
I would make the optional anti-tank support unit a definite one, since the original division had 24 anti-tank guns, which is exactly the number of the ingame unit. No regular artillery unit, but one support artillery unit, although the historical unit had 36 artillery guns those had limited firepower. (12 guns with 100mm and 24 with 75mm, thus of rather weak firepower.)

French Infantry Division 1940

What is faster than a pizza delivery, well, some argue it is the United Baguette Division, so, let’s look at the changes for the French Infantry division of 1940:

There should be a reduction of the regular artillery battalions to just one. Instead of the support anti-tank unit a regular anti-tank battalion and optional an additional one as support, similar to the US and Soviet division, because the French division had 58 anti-tank guns historically.

Polish Infantry Division 1939

Now, of course this is for Hearts of Iron IV and not Space Invaders, nevertheless, some update on the Polish Space Division is necessary, the changes for the Polish infantry division of 1939, is as follows:
The once optional support anti-tank unit is now definitely a part of the division, because the historical division had 27 guns. Since the historical artillery was quite similar to that of the Italian division, no regular artillery battalion neither, just one support artillery unit.

Romanian Infantry Division 1941

And the last division layout for this video, the setup of the Romanian Infantry Division of 1941.
Now, the updated Vampire Legions are as follows:
The historical division had 30 anti-tank guns, hence either a regular anti-tank battalion or support anti-tank unit are possible. The artillery battalions should be reduced to one support artillery battalion, since their firepower is just a bit more than that of the Polish or Italian divisions. (36 field guns with 75mm and 16 howitzers with 100mm present. )

Suggestion for Proper Artillery Battalions

Now, once I realized that the ingame artillery battalions are actually the size of 3 historical artillery battalions, I added a suggestion to the Paradox Forums. Maybe there is a good reason for this, but I haven’t found one so far. Because, well there are enough slots in the division designer to support very large units. Additionally, the other battalions have mostly correct values for manpower and equipment numbers that are on par with historical numbers.
If you think the same or otherwise, please check the link below to my suggestion post on the forums and add your thoughts and/or support there.

HOI 4 – Historical Infantry Division Layouts – Early War #Hearts of Iron

Intro

In this video I will cover several Infantry Division Layouts from World War II. Although certain parts of the content is tailored for Hearts of Iron players most of the information is military history, only the initial remarks are mostly Hearts of Iron and methodology specific, so just skip ahead on click on the annotation on the screen.

Hearts of Iron IV

Be aware though that these layouts are aimed at being as historical as possible within the Hearts of Iron division builder, thus I am not sure how well they work in HOI 4. This is first and foremost a military history channel, thus I am mainly here for the historical flavor, the German accent and not to support your ambitions in conquering the world, at least for now.
I won’t use the division builder, since I generally try to avoid any copyrighted material and it would actually make everything more complicated and time-consuming. Yet, you will get in one shot the proposed HOI 4 setup and the historical setup together, so you can basically copy it and also learn a bit about the real units too. On the homepage, you can find the proper high resolution screenshots of these layouts see the link on screen and in the description.

Methodology & Accuracy

Some words about methodology and accuracy, if you want to discuss these layout listen to this section very carefully and if you can’t wait for the layouts, you might skip ahead by clicking the button on screen.

Well, figuring out the correct layouts can be quite complicated. Here are a few reason why. You need to be aware that some divisions – especially tank divisions – changed quite considerably throughout the war, thus I usually provide a date for each layout. Another major pitfall is the naming, what one country called a regiment was sometimes something different in another, thus this it was not as straightforward as it seems. Also there were even quite some difference within each country, e.g., a German tank division in 1939 had way more tanks than in 1941, or an US Army Battalion in 1942 was usually larger than an US Army Battalion after the reorganization of September 1943, well, except for two divisions of sixteen armored divisions.
Hence my approach was as follows, it consisted of looking at the data in hearts of Iron, checking the historical division layouts then compare these information to equipment and manpower tables to see if the numbers match for different units.

This process revealed quite some interesting information about hearts of Iron too. First I looked at the data of Hearts of Iron, namely how many manpower and equipment each unit had. This confirmed my assumption that the so called support companies are more like support battalions, only the three smallest ones the engineer, AA and artillery company have 300 men, the others have 400 or even 500 men. Whereas companies were usually around 100 to 200 men. Furthermore, the number of artillery guns for an artillery battalion in game is 36, whereas in real life this was the number of three battalions at least for the German and US Army Infantry division. I don’t know if this is an error on behalf of paradox or if an artillery battalion in game actually should represent a regiment or maybe it is for gameplay balancing reasons. For this video I assume that an artillery battalion in game, is also an artillery battalion historically, if this is not the case, just divide the number of proposed artillery battalions by 3 and you should be fine.

The second step was to look at the organization of these units and the third step was to look at the number of equipment tables and compare if it matches the organization, because the organization can sometimes be misleading. As an example. although an US Army infantry division didn’t have a dedicated anti-tank battalion like a German infantry division, but it had 57 anti-tank guns whereas the German division had only a few more with 75, but some these were also part of the recon battalion, so one might argue that the US Army Infantry division should have a dedicated anti-tank unit in-game if the German Infantry division has one or both should have none.
As you can see it is a bit complicated, thus, take all the following information with a grain of salt, because I had to use a wide variety of sources of different quality and level of detail, which is problematic in itself, but additionally the chances for errors increases due the variety and amount of data. To balance this, I usually added a short explanation why or why not I went with the proposed setup and provide the basic data for my reasoning.

German Infantry Division 1940

So, let’s get started, the Allied Grand Strategy in World War II was “Germany First” and it worked out, so let’s begin with a German Infantry Division from 1940.
It consisted of an Engineer Battalion, an Anti-Tank Battalion, a Recon battalion, an artillery regiment, which consisted of a heavy artillery battalion and 3 artillery battalions, additionally a signal battalion and finally 3 infantry regiments each with 3 infantry battalions. Now the division didn’t have a dedicated medical battalion, but it had 2 medical companies, a field hospital and two medical transport columns with almost 700 men in total, thus I would say this qualifies as a medical battalion. Additionally, it also had maintenance and logistics units attached. So this unit was very well equipped, the only unit type it definitely didn’t possess was an anti-aircraft unit, the division used solely heavy machine guns for anti-air defense. Now, the German infantry division had almost 17 000 men, whereas most other divisions have less than 15 000 men, thus my proposed HOI setup would be as follows:

For support units, an engineer, anti-tank, recon, signal and medical unit. The regular 3 times 3 infantry battalions should get an addition of 2 battalions due to the large amount of men in the division and finally 4 artillery battalions.
Note that for all divisions the non-combat units: logistics, medical and maintenance are the most debatable, because in my sources this information is often not included or limited. Furthermore, their functions sometimes were performed by non-divisional units in several armies.

Soviet Rifle Division 1941

I hope you have your Hammer and Sickle ready, next is a Soviet Rifle Division from April 1941.
It consisted of an a signal battalion, a medical battalion, a supply battalion, an Anti-tank Battalion, an anti-aircraft battalion, a Light Artillery Regiment with 2 battalions, a sapper battalion, one Howitzer Regiment with 2 battalions and 1 heavy battalion, a recon battalion and 3 infantry regiments with 3 battalions each. Yeah, this one seems to tick off all boxes. Yet, in total the division had only around 14500 (14454) men.

But let’s take a closer look at the data, now the number of five artillery battalions sound impressive and the firepower is also clearly more than that of the US and German unit. The number of heavy artillery above 150mm is the same, yet whereas the US and German units use 105 mm guns, the Soviets used 122mm howitzers although 4 less, but additionally they had several 76mm howitzers and cannons, which means that the firepower in artillery at least equal if not greater than the German division. Furthermore, the total number of 54 anti-tank guns is lower than the German division, but similar to the US setup.

Based on this data my proposed HOI setup is as follows:
For support units, an engineer, medical, recon, signal and logistical unit. Then the regular 3 times 3 infantry battalions, to these add one anti-tank and one anti-aircraft battalion. Finally, definitely 4 if not 5 artillery battalions.

US Army Infantry Division 1943

Time for a little bit of freedom, so let’s look at the US Army Infantry division layout from July 1943. It consisted of a Medical Battalion, an Engineer battalion, a divisional artillery unit with a heavy artillery battalion and three artillery battalions. And finally 3 infantry regiments each with 3 infantry battalions. In total this division had around 13000 men.
Now, here is the problem the US Army division had a recon unit, a signal company, a quartermaster company and a maintenance company, but all these units had less than 200 men unlike the German units before. Yet, looking at the data I realized that the division in total had 57 anti-tank guns, which was just short of the 75 from the German division that had some in deployed in their recon battalion, hence my proposed HOI setup is as follows:

For support units, an engineer, an optional anti-tank and a field hospital unit. Then the regular 3 times 3 infantry battalions and finally 4 artillery battalions. Now, the German recon unit consisted to large part of cavalry and only a few armored cars, whereas the US unit had halftracks and 13 armored M8 cars, thus only could also argue that a recon unit could be added as an additional support unit.

British Infantry Division 1939

Next up something for those people that love tea, the British Infantry Division in 1939 of the British Expeditionary Force. Now the British unit names were a bit different, they used the names Brigades and Regiments, although those units were usually had the manpower of Regiments and Battalions, I will use the original names, but symbols that are closing in representing their actual strength.

The division consisted of a Division Cavalry Regiment that was mechanized, an Engineer Battalion, a Divisional Artillery Unit that consisted of 3 field artillery regiments and one anti-tank regiment, furthermore a Supply Unit and a medical unit. And finally 3 infantry Brigades each with 3 infantry battalions. In total the division had a bit short of 14000 men.

Based on this information my proposed HOI 4 setup would be:
For support units, an engineer, a medical, a recon, an anti-tank and a logistics unit. Now, although the number of anti-tank guns was only 48, the unit had a large amount of anti-tank rifles and the French provided anti-tank guns for the British divisions, thus an anti-tank unit seem justified. Then the regular 3 times 3 infantry battalions and finally 3 or maybe 4 artillery battalions, because the British division fielded 72 field guns of the 18 and/or 25 pounder type. Furthermore, the unit was quite well motorized and even mechanized with 140 Bren carriers, thus one actually could replace the regular infantry with motorized or mechanized infantry.

Source: Nafziger (Note: that it lists 147 pieces of the 25mm anti-tank gun, a number that seems completely off and likely is, because it was a French anti-tank gun and I doubt they received so many of them.)

Japanese Infantry Division 1940 Standard B

Now the war situation may not necessarily develop to your advantage, nevertheless let’s look at the Japanese Infantry division Standard B around 1940, note that these division varied to a certain degree.

It consisted of an engineer regiment, a transport regiment, a recon or cavalry regiment, Division medical services, a field artillery regiment with 3 field artillery battalions and three infantry regiments with 3 battalions. Note that these artillery battalions were equipped with 75mm guns, thus having far less firepower than all other nations. Yet, these divisions had a very high amount of manpower, depending on the setup between 18000 to 21000 men, thus even outnumbering the German division by far.

Based on this data my proposed HOI setup is as follows:
For support units, an engineer, a medical, a recon and a logistical unit. The regular 3 times 3 infantry battalions should get probably an additional 6 battalions. Finally, I think one artillery battalion or at most 2 battalions considering the rather weak firepower of the 75mm howitzer in contrast to the equipment of other nations.

Italian Infantry Division 1940

Everyone loves Pizza, but I only can offer you one slice, time to look at the Italian Infantry division of 1940.
It consisted of an engineer battalion, a legion of fascist militia that consisted of two battalions, a regiment of artillery with light gun battalion, a light howitzer battalion and a regular howitzer battalion, finally two infantry regiments, which consisted of three battalions each. Yes, only two infantry regiments, this was the so called binary division layout the Italians used. It also had an anti-tank company, but in total just 24 anti-tank guns. In total this division had 13000 men. (In terms of artillery it had 12 guns with 100mm and 24 with 75mm.)
Now, my sources on this one are a bit varied, I have good German source with the overall numbers and high-level organization, but for more detailed information I rely on the Handbook on the Italian Military Forces from 1943, which was created by the US Military Intelligence during the war, so it might not be 100 % accurate, but so far these handbooks are usually quite reliable in terms of unit organizations.

Based on this information my proposed HOI 4 setup would be:
For support units, an engineer unit and with three eyes closed an anti-tank unit. For infantry, we use the 2 times 3 infantry battalions and add an additional 2 battalions, but maybe a third or even fourth, because the total number of men is similar to that of an US Army infantry division, which had way more support units. Finally, I think one or maybe two artillery battalions, because in total there were 24 guns with 75mm and 12 howitzers with 100mm present.

Soruce: Handbook on the Italian Military Forces, August 1943, Military Intelligence Service – TME 30-420

French Infantry Division 1940

Well, after some Pizza, who doesn’t want to enjoy a baguette? So, let’s look at a French Infantry division of 1940:
It consisted of a recon group, a field gun regiment with 3 battalions, a howitzer regiment with one heavy howitzer battalion and a regular one, 3 infantry regiments with 3 battalions each. Additionally, there were several anti-tank companies with a total of 58 anti-tank guns and 2 engineer companies, which were originally organized in a battalion but reorganized in 1939.
In total the division had around 17 500 men. But note that in this case my sources are quite sparse and of limited quality.

Hence my proposed HOI 4 layout is as follows:
For support units, an engineer unit, an anti-tank unit and a recon unit. The regular 3 times 3 infantry battalions should get an additional 3 battalions, because the division has more men than the German division and also less support units. For the artillery battalions, I think three are in order, because it had 36 field guns with 75mm, 12 howitzers with 105mm and 12 howitzer with 155mm.

Polish Infantry Division 1939

So, in case you want to go into space, here is the Polish infantry division organization for 1939. In this case my data is way more limited than with the previous divisions, especially in terms of the support units, so keep a bit more salt ready.

The division consisted an Engineer Battalion, a light artillery regiment consisting of two light artillery battalions and one regular artillery battalion. Yet, it also had a small detachment with bigger guns, but overall it couldn’t compete with the US or German division in this regard. And as usually it had 3 infantry regiments each with 3 infantry battalions. It had several medical units, but I have no numbers, nevertheless I assume it would be sufficient for a medical battalion. Similar to the German division the Polish division has more than other countries with around 16 500 men.

The division had quite many companies attached, like several anti-tank, a bicycle, an MG, and a cavalry company. Thus, one could argue that these units qualify together as a recon and/or anti-tank unit, although the total number of anti-tank guns was only 27 guns, which is less than half of the US Infantry division anti-tank guns. Based on that data my proposed HOI setup is as follows:
For support units, an engineer, a medical, maybe a recon and with two eyes closed an anti-tank unit. The regular 3 times 3 infantry battalions should get two additional battalions, 2 artillery battalions and maybe a third artillery battalion.

Romanian Infantry Division 1941

And the last division layout for this video, the setup of the Romanian Infantry Division of 1941.
It consisted of a recon battalion, an engineer battalion, a field artillery regiment with 2 light battalions and a regular battalion, an artillery regiment with a light field artillery battalion and regular battalion and 3 infantry regiments with 3 infantry battalions each.
Additionally, it had an anti-tank and anti-aircraft company, furthermore each of the regiments had an anti-tank company, but these units were usually not sufficiently equipped. In total it would be around 30 anti-tank guns. About the signal and medical units, my source for the layout on the Romanian units is good, but it doesn’t include any non-combat units. Yet, since the author notes that the communication and many equipment was quite poor, one can assume that there was no state-of-the art signal unit present and the medical services were probably lacking. The division in total was a bit short of 17 000 men, thus it is quite a large force, especially considering the low numbers of additional units. (Source: Axworthy, Mark: Third Axis, Fourth Ally: Romanian Armed Forces in the European War, 1941-1945, p. 39-42)

Based on this information my proposed HOI 4 setup would be:
For support units, an engineer, a recon and with two eyes closed an anti-tank unit. The regular 3 times 3 infantry battalions should get probably an additional 3 battalions. Finally, I think two artillery battalions, because in total there were 36 field guns with 75mm and 16 howitzers with 100mm present.

Italian Forces and Industry in Early World War 2 (1939-1940)

Intro

Prior to World War 2 both Hitler and Mussolini were boasting about their military forces to each other. Mussolini announced in 1934 that he can mobilize 6 Million soldiers, in 1936 he increased the number to 8 million and in 1939 to 12 million. (Schreiber, Gerhard: S. 54, in Deutsche Reich und der Zweite Weltkrieg, Band 3) If those numbers sound a bit off, well, Operation Barbarossa was largest military invasion in history and it was conducted by around 4 million soldiers. Nevertheless, the Italians managed to mobilize around 3 million soldiers, yet these soldiers were basically worse equipped than the Italian troops in World War 1. Quite in contrast to the German and Japanese forces, the Italian forces were not ready for a war against any major force.(Schreiber, Gerhard: S. 54, in Deutsche Reich und der Zweite Weltkrieg, Band 3)

The question is why the Italian Armed Forces were not ready, there are several reasons for this, in general the Italian and Fascists system was quite inefficient. First, the Italy had a limited amount of industries, which weren’t properly prepared for arms production. Second, the allocation of resources and organization was limited, additionally similar to Germany and Japan, Italy also had a severe lack of resources. Third, the wars in Ethiopia and Spain required resources that the Italians couldn’t spare, after all those conflicts dragged on far longer than anticipated. As a result the Italian forces were not ready when the war started in 1939. Mussolini was quite aware of this problem, after all, he insisted on a period of peace during the negotiations of the Pact of Steel – “Stahlpaket” with Germany and didn’t join the war until June 1940 by declaring a war on France. (Schreiber, Gerhard: S. 54-56, in Deutsche Reich und der Zweite Weltkrieg, Band 3)

Organization before the war

At first, some word about the general organization of Italian Army before the war. Like other countries Italy drew lessons from experiences in Spain and Ethiopia, yet their forces were still in reorganization when the war started and the industry couldn’t match the requirements for the required motorization or even the basic equipment that was needed.

In 1937 the Italian Army restructured its divisions from the common system of tripartite to a bipartite system, the so called “binary” system, where each infantry division only consisted of 2 infantry regiments instead of 3. Something that is also portrayed in Hearts of Iron III and Hearts of Iron IV, as you can see here for the division builder of an Italian division in 1939 and a British division in 1939, but be aware though that the Hearts of Iron IV basic divisions layouts lack artillery regiments, furthermore the so called support companies historically usually were battalions, as you can see here with a basic German infantry division from 1940. Yet, from a game design perspective it makes sense to call them companies, because so you can’t mix them up with your regular battalions when writing about division compositions on the forums. Anyway, if you want to learn more about unit organizations, check out the playlist on my various organization videos.

Now, the intention of the binary system was to make the units more capable for mobile warfare, the units should be easier to command and be more mobile. The lack in manpower should be countered with modern equipment, yet, this was wishful thinking because the Italian industry couldn’t even provide basic equipment in sufficient numbers. On the outside the binary system created more divisions, but basically this was only useful for propaganda and didn’t increase the capabilities of the Italian Army. (Schreiber, Gerhard: S.56-57 , in Deutsche Reich und der Zweite Weltkrieg, Band 3)

Next up, is a brief look at the Situation in September 1939 and then a more detailed look at the state in June 1940.

Situation in September 1939

Let’s look at the state of the Italian forces in the beginning of the War in September 1939, when Italy was still at peace. In short the Situation of the Italian Armed forces in September 1939 was abysmal. Yet, you need to keep in mind that Italy didn’t enter the war before June 1940.

Army

At first the Army, it had had 67 divisions without the units in Ethiopia, these divisions consisted of
43 Infantry
3 Tank
2 Motorized
3 Fast division
5 Alpini, and
11 other division for special purposes.

Yet, only 16 of these division were completely restructured, furthermore there was a lack of artillery, tanks, transport-vehicles, anti-tank and anti-aircraft guns. Even basic supplies like quality food was lacking, so basically the Army had a severe lack of almost everything. (Schreiber, Gerhard: S.58-59 , in Deutsche Reich und der Zweite Weltkrieg, Band 3)

Navy

The Navy was better equipped in terms of basic supplies like food and ammo, but it also lacked anti-aircraft capabilities on its ships and in its bases. Yet, there was severe lack of fuel. Still, in comparison with the other branches the Navy was the best equipped and prepared.

Air Force

The Italian Airforce the “regia aeronautica” also had major problems, there was a vast amount of different aircraft types and additionally the ground crews were of limited quality, this lead to low number of operational aircraft of less than 50 % in September 1939, when only 1190 planes were operational out of 2586. Furthermore, most aircraft were usually underpowered and under-armed. [Something most War Thunder players are highly aware off “Spaghetti guns”.] (Schreiber, Gerhard: S.58-59 , in Deutsche Reich und der Zweite Weltkrieg, Band 3)
As a result of that dire state of the Armed forces and the severe lack of ammo, weaponry, fuel, transport capacity and personnel, the ministry for war production in December 1939 advised Mussolini that only an army of 73 division would be feasible instead of the originally planned number of 126. Yet, still the industry wasn’t capable in equipping those units sufficiently til the entry of Italy in into the war in June 1940, but nobody assumed that Italy would enter the war that early. Well, seems like Mussolini had a tendency for premature – declarations. (Schreiber, Gerhard: S. 58-59 , in Deutsche Reich und der Zweite Weltkrieg, Band 3)

The Situation in June 1940

Now, after the Italian declaration of war in June 1940 the situation was a bit different, but not much, but let’s take a more detailed view.

Army

First the Army, in June 1940 Italy entered the war with a total of a bit less than 1.7 million soldiers (1 687 950) and a total of 73 divisions..
Whereas in 1915 the Italian army joined the war with more men, it was also an army that had similar quality weapons and equipment like other majors, but in 1940 this was clearly not the case. (Schreiber, Gerhard: S. 59 , in Deutsche Reich und der Zweite Weltkrieg, Band 3)

Of the 73 divisions only 19 had the required amount of personnel, equipment,weapons and transport capacity. Another 34 division were operational, but lacked personnel (25 %) and transport capacity. The last 20 divisions lacked more than 50 % personnel, a significant amount of equipment and 50 % of transport capacity. (Schreiber, Gerhard: S. 59-60 , in Deutsche Reich und der Zweite Weltkrieg, Band 3)

The infantry formed the mainstay of the Italian army, but the firepower of an Italian infantry division was according to Gerhard Schreiber only about 25 % of a French Infantry division or around 10 % of a German infantry division. (Schreiber, Gerhard: S. 61 , in Deutsche Reich und der Zweite Weltkrieg, Band 3) Now, I don’t know how the author determined those numbers, but here is a direct comparison on the numbers of a Italian and German Infantry division with the intended equipment and personnel:

Comparison between an Italian and German Infantry Division in 1940

Ital. ID (1940) German ID (1940)
449 Officers 518 Officers
614 NCOs 2573 NCOs
11916 Men 13667 Men
12 Heavy howitzers (sFH) 15 cm
6 Heavy infantry support guns 15cm
12 100mm howitzer 36 Light howitzers (lFH) 10,5 cm
24 75mm guns 20 Light infantry support guns 7,5 cm
8 65 mm mountain guns
8 47mm anti-tank gun 75 3,7cm anti-tank guns
8 20mm anti-air guns
30 Mortar 81mm 54 mortar 8,1 cm
126 Mortars 45mm 84 mortar 5cm
80 Heavy machine guns 110 Heavy machine gun
270 Light machine gun 425 Light machine guns
(Source for the German Division: Alex Buchner: Handbuch der Infanterie 1939-1945)

The most important differences here are the low number of NCOs in the Italian division, NCO form the backbone of every army, thus this lack of leadership definitely didn’t improve the overall quality of the division. Furthermore, the biggest Italian gun had 100mm and only 12 were assigned to a division, whereas the Germans had 3 times that and additional 18 guns with 150 mm of caliber. Now, the Italians had a variety of guns ranging from 75mm to 20mm, but almost all in low numbers and of various types this is basically a logistical nightmare with limited firepower, especially in combination with the severe lack of transport capacity and weak industry. Also in terms of infantry support weapons like mortars and machine guns the Germans had an advantage.
Based on that data, I assume the firepower difference was calculated based on how much shell weight each division could deliver for a specified amount of time. At first you can’t spot a 1 to 10 difference, but you need to consider the weight differences of higher caliber guns. Let’s take a look at the weight of a 15 cm howitzer shell, it was about 50 kg whereas the 10,5 cm howitzer could only deliver a shell of around 15 kg. The shell weight and thus the resulting firepower can easily missed, if one looks only at the caliber alone.

Resource Problems

Yet, this comparison assumes that the division was fully equipped with artillery, but Italy had a severe lack of modern artillery and anti-aircraft guns, it lacked about 15 000 modern artillery guns and the industry could only put out less than 100 per month. This meant that the Italians had a limited amount of modern artillery and since that wasn’t bad enough there was also a lack of ammo. The situation with tanks was not much better and those tanks were also to a large degree simple light tanks of limited combat capabilities. (Schreiber, Gerhard: S. 61-65 , in Deutsche Reich und der Zweite Weltkrieg, Band 3)
Resource Problem
Furthermore, the Italian industry had a lack of resources, how dire the situation was can be best expressed with some numbers. These are the percentages on the Italian estimate for meeting the requirements of 1940:
Artillery (all types) 6 %
Ammo, small caliber 25 %
Ammo, medium caliber 7 %
Ammo, heavy caliber 10 %
Rifles (Model 1891) 35 %
Machine Guns 10 %
Mortar 81mm 70 %
Ammo, Mortar grenades 81mm 10 %
Planes 42 %
Engines 40 %
Bombs under 1000 kg 40 %

(Schreiber, Gerhard: S. 66 , in Deutsche Reich und der Zweite Weltkrieg, Band 3)
One can assume that Mussolini would get führious from the “insufficient resources” icon popping up all the time, if he would play Hearts of Iron.
One can assume Mussolini would have gone mad from the “insufficient resources” icon popping up all the time, but he was probably already mad already.

Navy

Now, the Italian Navy was by far the strongest part of the Armed Forces. For the Mediterranean the numbers of the Italian fleet were quite considerable: (Schreiber, Gerhard: S. 77 , in Deutsche Reich und der Zweite Weltkrieg, Band 3) Here is a comparison between the Italian, British and French Fleets assigned to the Mediterranean.

Italy UK France
Type Number Tonnage Number Tonnage Number Tonnage
BB 4 117240 5 148350 5 116165
CV 0 0 1 22600 0
CA 7 70000 0 0 7 70000
CL 12 74630 9 51000 7 51723
DD & TP 125 120335 35 48200 57 67250
Submarine 113 88000 12 13000 46 49000

Note that 2 of these 4 Italian battleships weren’t fully operational yet in June 1940. Also, due to the lack of the Italian industry these numbers can be a bit misleading from strategic point of view, because the British had way better capabilities to construct new ships in contrast to the Italians, thus losses on the Italian side had a greater strategic impact. (Schreiber, Gerhard: S. 75-78 , in Deutsche Reich und der Zweite Weltkrieg, Band 3)

Furthermore, these numbers don’t represent the quality of the ships, its crews nor other important factors. Nevertheless the Italian ships meet the international standards unlike their army units. Although, there was some major problems. First the lack of air coverage by land based aircraft due to range and insufficient coordination with the air force, of course the aforementioned missing naval air arm was also a major flaw in the Italian Navy structure. Second, the power plants of the ships had limited reliability and there was a general lack of anti-aircraft weapons for the ships and harbors. Third, the lack of a radar on Italian ships had a crucial impact during the Battle of Matapan against the British. The Germans had their own radars, but only after the loss at Matapan informed the Italians about their radar and provided assistance. (Schreiber, Gerhard: S. 75-78 , in Deutsche Reich und der Zweite Weltkrieg, Band 3)

Air Force

Now, let’s take a brief look at the Air Force. In June 1940 the “regia aeronautica” had 1796 operational planes and 554 non-operational ones (total 2350), thus it clearly had a higher readiness ratio than in September 1939, the total number of planes is actually a little lower than in 1939, this is probably due to the fact that this number doesn’t include training planes. Yet, a major problem was the lack of a proper naval aviation, which is quite problematic for a country that has a quite extensive coastline. Although Italy had some good air frame designs it lacked mostly powerful engines and also its production capabilities were not the best to put it very mildly, well, time for an international comparison. Schreiber writes about the Italian aircraft industry the following:

“Italy basically achieved between 1940 and 1943 an average output per year that was slightly above the British monthly average of produced aircraft in 1943.”

(Translated & cited from the German version of Germany and the Second World War – Volume III)

“Italien erreichte also zwischen 1940 und 1943 im Durchschnitt eine jährliche Fertigungsquote, die etwas über dem lag, was die britische Luftfahrtindustrie 1943 in einem Monat ausstieß.”

(Schreiber, Gerhard: S. 71 , in Deutsche Reich und der Zweite Weltkrieg, Band 3)

Conclusion

There is a strong tendency to give the Italian soldiers a bad reputation for being cowards and unreliable, which certainly is influenced by the fact that in World War 1 the Italians turned against their former Allies the German and the Austro-Hungarian Empire.

Nevertheless, in World War 2, Italian soldiers fought as brave as their allies and foes, thus there is no reason for the continuous disrespect about their combat capabilities, which was mostly a result of the poor state of their industry, equipment, weaponry and supply situation.
As said before soldiers deserve our respect, even if we don’t share their side and/or views.
