Perhaps the big issue here is the USA did no always have the best gear, my view out of the big players till the Abrams they had poor tanks. High silloutte little or no giro poor guns with the saving grace of good fire control.
Really only any good for static defence but even then the poor gun negated the good fire control for the time as you could hit targets but not penetrate them.
The first Abrams suffered from this even more so as it had a leap forward in fire control & vision but could not capitalise on it due to the poor gun. Keeping manufacturing simple & the artillery having a say in it & wanting a long lasting barrell meant compromises in penetration if I remember correctly.
The game also provides you with lots of nice Russian toys but in reality the nice ones are not that common so while the USA has huge stocks of Abrams, Apaches etc they will normally be facing average Russian stuff.
The T-72BM was it common without looking I would guess not there would have been far more T-72Bs
So the problem you are having is you are depicting a rare battle vs the 1 or 2 battalions equipped with the good stuff rather than fighting the standard formations that are the norm
