Additional older MBT for Insurgents and Irregular Militia.
I think 2 T-62's in hands of these fractions is a bit off.
i'm not trying to say that two t-62 are OP or something like that.
These fractions are fighting with what they have and two fully functional t-62 at the same time should be rare for those fractions instead i suggest to add T-55A that will be a bit worse than t-62 but still can hold bradley's APFSDS round in front upper and lover plates,"3UBR6" and "3UBR8" round's respectively in hull, turret cant be penetrated with these autocannon shells in front and sides, but T-55 will not stand any LAT or HAT rockets neither the tank shell's or all sorts of TOW's that will penetrate his front hull and turret armor.
For this tank specifically could be added the "BR-412D" /APCBC shell that contains some explosive inside and when shell penetrates the armor it explodes inside that cause big damage to the target.
"BR-412D" should have lower penetration than his APFSDS/"3BM25" shell but due to age of the tank there isn't much APFSDS left in storage and because of that, ammunition load would consists of 20 "BR-412D" shell's, 10 "3BM25" Shell's, 10 "OF-412" high explosive(not anti-tank) shell's and 3 "3D3" smoke shell's.
It's hard to say what these shell's could penetrate in front armor and what could not but these light armored vehicles: BMP-1, BMP-2,BTR-80,BTR-82A,STRYKER'S, and Bradley. "BR-412D" and "3BM25" shell's should be able to penetrate front armor. in case of penetration by "BR-412" in side of enemy tanks it should take of 1/3 hp of tank but not make any damage to part's, if "BR-412" hit's engine it destroys it and take 1/3 of enemy tank's hp. in case of penetration by "3BM25" it deals same damage as t-62's "3BM-4" shell.
(this part is how i would balance that tank)
armor: Two Bradley's
armor: 1 BMP-1 and 1 random t-62 OR t-55
