M2A2 and M3A2, they were the uparmoured version of the Bradley, (more armor in exchange for the firing ports) and they were predominant by 1990.
Because I missed this, the A1 variants are the first uparmored/no side gun port version of the Bradley. The A2 variant is a very late addition for the war, likely only fielded to places like Fort Hood or piecemealed in elsewhere as A1s are destroyed. I was gunning an M3A1 in Germany until I left in '98 and never saw an A2 until several years later when RIPing with a heavy unit in Iraq.
For der Heer, if the G11 comes in, another 5.56 assault rifle, the G41 needs to be there, too. If my research and interviews are right, the G11 was never really meant to have survived this far into the war, all of its users and ammo expended. The BOIP was only to first echelon mech infantry, everyone else (who was expected to survive the initial push by the Soviets) would be issued G41s and be able to
suck off draw supplies, to include magazines, from the giant American supply system. Otherwise, I was shooting a G36 for a not-Schützenschnur range day with our sister-unit in '97 or so (and a G3 with my buddy's wife's father's reserve unit.) Likewise, the actual changeover was from P1 (8-shot Beretta) to P8 (Beretta stats) but I'm cool with that or the P7 (for tradition).
BMD: It's never been a core vehicle and I've always used BMP stats when I felt the need to make the distinction. (I never had the Soviet vehicle books until well after I stopped playing.)
Zip guns: Conversely, they've been a core weapon since 2e, so they need to stay for tradition's sake. But we don't need more than one.
