I love the kit. Partially because I did the historical research for these and have my hand in them. I may be a small bit biased.
I'm going to use English descriptions to save my fingers contual typing of Aztec weapons/body armor.
The kit, as it is, can make 10 each of elite Infantry in full suits, 10 medium infantry in a loincloth and Aztec gambeson, and 10 light infantry. This makes it easy to plan army building
The elite infantry can be used to make 2nd captive, Jaguar warriors, coyote priests, and shorted ones.
At a stretch, you can also probably convert otomi warriors from the otomi elite warrior society. The body suit is not set up for eagle warriors but I'm sure it could happen given sufficient conversions.
The medium armored troops are excellent. All of you weaponrsoptions (spears, macahuitl, various ranged) are available. As are novice warriors (with topknot) and 1rst captives (without topknot, generally armed with maca and shield)
The same applies to the unarmored bodies as with the medium. Plus, because there are only 4 shields out of the 6 bodies, it would make sense to build some of your light troops as ranged infantry.
If I had everything I wanted the kit would also have a butterfly back banner and a few more heads without topknots.
