That is a very bold and completely unfounded and crap statement.
Read: "sitting behind an ocean" the US did what other countries wanted to do, but could not afford due to total war and weapon cost being a major issue. The SU wanted decent semi automatic rifles, but could not afford them during the war, and switched production to a cheap PPSh. The Germans produced the same number G43 rifles in 1943-1945 as they did the StG44. The AKM was adopted in the Warsaw Pact because it was a cheap rugged design that could easily be mass-produced for total war (unlike the SKS), not because of being better on the battlefield.
In-game that would mean that divisions equipped with these rifles would be cheap to equip, and obviously still better than pre-war designs, but not quite as good as post-war battle rifles.
In that case, explain adoption of M-16.
Putting arise yet another very bold statement of calling the post war US army "small and professional", when it was huge and conscripted.
Every army uses rifles for snipers and similar roles.
What about the FAL? It was loved by the said "banana republics". And was still a battle rifle, completely unlike the StG44.
2 millions is extremely little for a battle rifle used in 90 countries during 50 years. You should probably explain why it is so underused.
It is true that in WW2-style "total war" the AKM would do better (not the StG44, because it was too complex). But mainly for the reasons outlined earlier - cheap, rugged, easily mass produced.
Easier to use by soldiers with little training.
Poorly quoting wikipedia hardly works as an argument and is laugable in general, but OK.
Provide a good quote from a book, otherwise your lack of arguments is laughable even more.
The development of the 5.45 in the USSR, and the 5.56 in the US had 2 main goals.
1. Allow the soldier to carry more ammo and therefore bring more fire-power to the battlefield.
2. Reduce rifle recoil while retain the accuracy of rifle rounds.
The Kurz cartridge did not allow the soldier to carry more ammo, the rifle and the cartridges were no lighter than contemporary rifles. And while recoil was reduced, accuracy suffered due to lower bullet speed.
So no, the 5.45 in the USSR, and the 5.56 in the US had little to do with the Kurz.
Kurtz cartridge allowed to have better accuracy then SMG round, while having reasonable recoil.
Kurtz accuracy is enough for WW2 weapon that is not sniper rifle.
German army was planing to eventually replace both it`s SMGs and rifles with STG44 for regular troops.
STG44 was shorted and more handy in close combat then K98 or G43.
5.56 rounds were developed because 7.62 round was not good for burst-fining due to having too much recoil.
5.56 round is worse at long range then 7,62. Hence, the 5.56 sacrifices long-range accuracy, for some reason(why?).
5.56 ARs replaced both rifles and army SMGs. Tompson, Sterling, M3, and others were in service of Nato countries up to 1990.
5.56 ARs were shorter and better suited for mechanized warfare and usage in viechles. Interestingly, how much does a weapon of person that is carried by APC weights is fairly irrelevant.
I think similarities are obvious.
But if you want to argue that development of 5.56 had nothing to do with recoil in semi-auto firing, go ahead, post your sources.
Also, go ahead and explain why did US army created M4 carabine, that has shorted barrel and lower mussle velocity while having the same bullet as M-16. They sacrificed long range performance. They must have some good reason, right? Maybe the reason is, even M-16`s 5.56 range is more than enough for a soldier. In that case, how can you argue that rifle round is not execive for infantry man, and Kurtz is not enough for most cases?
All in all, I would suggest you read some more or less recent works,
Daniel D. Musgrave, German weapons of War: Infantry weapons of the Third Reich, MOR Associates, 1985
not the immediate allied war trials.
It is quite similar to how German army itself rejected intermediate round when it was first offered in 1918, the same way allied rejected intermediate round till much after WW2 would end.
US infantry tactics during the war were not exactly that bad but overcomplicated squad structure tends to put a halt to efficiency.
Well, strictly speaking that is bad tactic to over complicate your squad structure.
Strictly speaking the entire basic German squad structure from the early thirties to the end of the war was nothing but logical extension of WW1 mindset. After all, why would essentially every rifle squad operate as machinegun team and go as far as cease distinguishion between rifle squad, "LMG" and "HMG" team in training manuals by 1941?
Not quite. Mortars made a huge difference. It is true Germans basically centered their tactics around MGs, but allies did not.
