This is a question to role-play gamers in regards to my ongoing tabletop RPG with my local group and mentioned here http://www.gamesas.com/topic/1487537-fallout-esque-apocalypse-tabletop-rpg/%C2%A0

My question is on the feasibility of non-canon vehicles, like the Bradley IFV and M1 Abrahms, based upon their real life counterparts and their availability in a postwar wasteland. Granted most up-to-date vehicles would have seen deployment to China and the Sino-American War Frontlines or areas where the government feared a followup invasion of Alaska or elsewhere but some locations may have depots that were buried in underground bunker garages.
