Welcome in the T-80 victims club!
We had a looong discussion on the Yahoo list about monkey models in Syria and Iraq, and how the Abrams should be invulnerable to nearly everyone, etc.
After much seeking of hard data, conclusion came up that the Soviet tanks from T-72A onwards were much better armored than many thought. Basically the game ratings which have been duly desearched, are as close to reality as gameplay allows.
I know this seems shocking after the last 15 years of Abrams report, but I also have spotted that last time i set up a 1985 US vs USSR battle, came up with one Abrams IP Squadron in defence against one squadron of T-80B/T-72M1. Got four of my tanks blown up first turn at 3km, had 30% hit chance, spent ages mainly driving them off until they turned their backs and I could stick'em one through the motor grating!
If you look at serious figures, you will see that almost every modern MBT is invulnerable to its own shots at long ranges on the front armor, as opposed to previous generation tanks (M48, M60, T55, Leopard1) which had much better chances of blowing one another up first hit.
And well, whose fault if the US army didn't invest in gun-fired ATGMs or active countermeasures?
Your best bet is: dig in atgm teams all over to surprise them, go for SP tank hunters and helos. Many attack helos, used with caution (skim the edges of the map, pop up at high altitude every once in a while if there is not too much AAD).
When you have no choice, like in this scenario, rush for the best positions (now you know them
), lay your tanks hill-top, and try to avoid cross-fires that will have enemy tanks on one side shoot your own other side tanks in the back.
Otherwise it's all luck
If that reassures you, it goes same deal against the Chinese, they have Type-85 III, with 125mm with DU, plus TI, and tey beat the hell out of my Abrams too!
So good luck for next time!
