Soviet T3 and T4 suggestion

My suggestions:
1.T3476
-price change to 240/85
-all machineguns' dps change to match guards' dp-28 machineguns
-add +10% accuracy veterancy bonuses for each level(+30% total)

2.SU85
-weapon penetration increased by 15%

3.KV-1
-move to T4
-price increase to 500/150
-add 180 additional health points
-all machineguns' dps changed to match guards' dp-28 machineguns

-add +10% accuracy veterancy bonuses for each level(+30% total)
-add +10% suppression veterancy bonuses for each level(+30% total)
-vet1 Secure mode ability replace with +20% rotation speed
-vet3 +20% rotation speed bonus replace with +20% armor

4.T3485
-price increase to 390/140
-replace Ram ability with Rush ability(50 munitions for 20 seconds of +20% acceleration/deceleration and maximum speed)
-add +10% accuracity on the move for each level(+30% total)

KV1 in Counterattack tactics can be replaced with Rapid Conscription. It suits better for counterattack spirit after all
I don't have ideas yet of how to make ram useful without making it op.

tl;dr
T3476 becomes spammable and AI oriented;
SU85 is built not for Focus sight only but for heavy AT;
KV1 is expensive but useful as metal shield and heavy AI platform;
T3485 becomes a good flanker;
as result SU is now far less commander(and RNG) depended and much more fun to play and to play against.

PS Swapping T3485 with T3476 and double T3476 call-in is a good idea too

Show Spoiler

Nah man, the vet bonuses would be OP as fuck.

Non doctrinal Guard Infantry to T3, nerf rof of T-70, make double T-34/76 call in and swap it for 85's. Done
