A graphic update would really do that system well. Ty Bomba is remaking it, but my fear (based on his comments) is that it will be essentially a completely different game.
One of the things I really liked about it was that it (mostly) accurately reflected the border cav units. Just because the rest of the game was BN/RGT-level doesn't mean the cav had to be. Instead of a couple of Squadron-of-Death counters for the 11th ACR, they were split out into troop-level units ("companies" to the rest of the world) and able to be properly dispersed per the deployment plans. Now, they weren't going to kill an entire Soviet MRR, but that was never their mission. A properly-spaced covering mission of 2 squadrons, with the tank companies / how bty's to reinforce where needed, can easily hold up that MRR for several turns, and completely de-synch the Soviet plan.
