Well, you are going to likely need more than 10 T-34 76/85s for a 1500 pt. Tankovy Battalion. Most of the advice for Tankovy Battalion is to max your T-34 76/85s (this will be 21 T-34 76/85s) You can play with making a list on
http://easyarmy.com/ using the free list from the V3 forces book, However, this list is not optimal, as it lacks
AA and Recon options, and it is best to have some of both. A better list is available in Red Bear.
Here is an example of a 1750 pt. list I was going to use from the V3 forces book to give you a general idea:
Headquarters
Tankovy Battalion
HQ: 1 T-34/85 obr 1943 with Cupola= 85
Combat Companies
Tankovy Company: 5 T-34 obr 1942 with Cupola, 4 T-34/85 obr 1943 with Cupola= 530
Tankovy Company: 5 T-34 obr 1942 with Cupola, 5 T-34/85 obr 1943 with Cupola= 585
Divisional Support:
Tank Killer Company: 5 SU-100s = 390
Heavy Mortar Company: 6 120-
PM-38 mortars= 145
Company Points: 1735
Like I said, it lacks any
AA or recon, which you are going to want. The 20 T-34s can kill weaker tanks and overwhelm infantry, while the 5 SU-100s can kill the stronger tanks. The mortars are there mainly to provide backup and pin down infantry.
