I just finished a box of Team Yankee BMPs and a platoon of Soviet infantry by Battlefront. I based the infantry on small washers instead of the unit bases. The BMP kit comes with a choice of either the BMP-1 or BMP-2 upper hull. I did both, then magnetized them so they can be swapped out depending in which I want to use. Not sure if the kit was designed for that, but it's a nice bonus feature.
