So, after thinking about this overnight, I have done a little research. In the last game I played, the Soviets had about 15,500 worth of VPs. I had a saved game from near the end and played it out so that I could check the number of TBs I was facing. By checking the Soviet record at the end, I was up against 5 TB - I thought I was going to be facing a TR - so this was a little bigger.
It also means that each TB is worth about 3,000 points. I could try to get more exact, but I'm too lazy and only really need this kind of comparison.
In this scenario, the Soviets have over 28,000 points. Using the logic from above, that means that I'm likely facing roughly 9 TBs along with their arty, AD, Helos and HQs. This might actually be 7 TB and a couple of MRB (Motor Rifle Bn) or something similar.
I had started my look at the Soviets and guessed that I would be facing two TR (6 TB and 2 MRB) so that is fairly close. I'm going to leave my first two options like that and add a third that includes an independent TB as an additional force.
