The Russian BTR covers a wide range of vehicles and quite a few are used in Alcovia. BTR-152, BTR-60/70/80, and BTR-50 are all used in Alcovia in one capacity or another. The models for these vehicles seem to be harder to track down than tanks. In this category it seems that plastic kits rule. There are a couple of gaming models and diecast toys. In each category I'll be addressing the basic vehicle as well as variants that I know of. I have decided to forgo posting pics of models and box art here as they will show up fine with a little Google-fu.
