Agreed: The T-72 would be the most desired (next to the M1A2) add-on, but how do we convince eSim to add it, if none of its customers own that equipment? A couple of thoughts:
1] Convince potential DoD customers that they would be able to build a more lethal OPFOR.
2] Sell the sim to customers who own the T-72.
However, maybe that would be giving the "bad" guys an unfair advantage.
