are these aa scale?
A better qustion to ask is “Are AA pieces in scale to these?”
AAs pieces are not all the same scale. Micro Armor made all their stuff in 1:285. They also had modern military units as well. It just happens that AA’s tanks happen to be close to this scale.
I bought their German half tracks, and they looked about right with the AA pieces. Micro Armor also makes modern units as well. Because its pewter, though, you have to paint them. And they’re pricey. Really good detail, but you pay for it.
FMG’s units are certainly a bargain in comparison. I looked into buying their pieces to replace my AA pieces, but the tab would have been in the high hundreds. But if you want to swap out some of FMG’s pieces, for say a panzer III or IV, then I’d go this route.
