In any case I find the selection of available vehicles to be rather odd. To my understanding the chechens used T-72 and T-62 and possibly some T-55 and T-64.
In particular Unit 176 T-80U: AFAIK few of these were available and it is highly unlikely that they would have ended up in chechen service.The few T-80s that were used in Chechnya were T-80BVs and the like.
Then the chanches of an advanced prototype like T-80UM1 (unit 177) serving under the rebels are absolute zero.
These units should be deleted and replaced with more realistic vehicles,like the T-62M and maybe T-72AV. I think also removing the ATGMs from the others tanks would be a good idea.
