I like to be able to use my Army Men in as many different ways as possible. Here are the Aztec figures made by Revell.
This model, by Safari, is the Quetzalcoatlus Pterosaur, they were alive during the time of the dinosaurs, 65 million years ago.
Perhaps we can use the Aztecs to fight ancient animals such as the Quetzalcoatlus?
It's much harder to fight giant monsters with pointy sticks and stone weapons than with rifles and hand grenades.
That gives another use for the Aztecs. Perhaps even use them as a lost tribe with lost animals in a 19th or 20th Century venue.
