I am guessing that I had received no further response from Major because he thought I was an idiot...perhaps he is correct. I figured out last night what the problem was. The key issue was the pregame preferences that I chose, and last night after another couple of rounds playtesting I figured out that the BMP's were not firing because they were using the standard AT-5 (i.e. not the AT-5i), and the standard AT-5 can't even penetrate an M-1 from the side. Yeah, yeah, go ahead, laugh at the Air Force guy.
abneo3sierra, thanks for the response. For the record, my guys were watching the M-1's from a woods, so the BMP's could see, but were not seen...and the BMP's weren't feeling suicidal.
