What are you talking about man, no offence? Are you sure you actually read my post? Especially the part where I referenced Armour doctrine?
Also, you are free to consult my playercard, I have quite few US games logged, probably alot more than you...
US At guns are the worst in the game? Jesus dude. Ever tried a Raketen, Soviet 45 mil? Take aim is the best AT gun vet ability in the game after TWP, and the only real drawback of US at guns is that their crews can be lasered down quickly by LMG grens. If you are facing a heavy tank and are having trouble penetrating it, there is always HVAP....
If they are using heavy tank, your atgun will be depop in no-time. Axis heavy tanks have been always really good vs infantry stuff. USF ATguns are only useful vs dedicated Axis TDs (stugs, jpz4, jagtiger and elephant). This and not being able to pen reliably make them worst ATgun ingame. Raken can camo, being in range to shot 2 or 3 times and retreat before getting wiped out.
