The units are ripped from Blitzkrieg game series. The first pack contains 4 units, here they are:
Chieftain uses panzer anims, all the rest use tank anims. All four have buttons included. Blitzkrieg is a relatively old game, so the models are low-poly by Civ 4 standards (lower polycount than vanilla units), and they might as well have somewhat simplistic textures (although, as you can see, all are 256x256 or at least 256x128). They don't have civcolor, gloss or damage states, so if anyone wishes to add those, you're welcome.
