Out of the essential core non doc abilities, the US appears to be missing:
1. mobile AT guns
2. Snipers
This is just like PE/CW from OF.
I dont' know yet, but it seems to me that the US squads can carry more than one purchase. I saw Psquieh buy two BARs for one squad in the twitch.
The same may apply to bazookas (60 muni each)- so squads may have more than one bazooka and maybe even a mix of munitions cache weapons.
That is the point, and essentially, every infantry squad can take a weapon, and as many weapons as they want, as long as there are enough munitions and squad members. Americans highly stress versatility of a core unit. One unit can have many roles. The basic engineer squad has an ability to pin a squad, which is pretty darn amazing. In the sense that Ost has a heavy muni reliance for upgrades, Americans also have that creed, and in the sense that Soviets rely on tanks to lead advances, Americans also have that need. Americans are a mix of heavy muni and fuel purchases, but not heavy as in every purchase is super expensive. It is in the way of many moderate costing fuel and muni purchases. I also noticed Americans don't seem to have too many units that cost a high amount of manpower. Everything is neither expensive, nor cheap, but everything is rather hard hitting, and rather durable.
