I have NO IDEA when this was last updated
That lists destroyed Russian tanks.
"Tanks (1646, of which destroyed: 967, damaged: 75, abandoned: 59, captured: 545)"
The T-90 is near the bottom
31 T-90A:
3 T-90S: ( that's supposed to be the "export" version )
10 T-90M:
44 total known destroyed or damaged or abandoned....... that should give you an idea of the numbers used but 10% of your force in the game would IMHO be too many unless you were trying to create an "elite" unit
