I just finished up an NVA squad. This is part of the massive 20mm collection that I have which about 1/2 way painted. I plan on getting these guys done before moving to my Pulp 28s and the 15mm modern, vietnam and colonials I have.
These guys are painted quickly using a tan coat of paint for the uniform, brown belt and boots and green webbing then given a light brown ink. This is the colorscheme for the NVA company I will be putting together. The guy waving and the guy ducking are both Kit Carson scouts.
Also here you can see the base green coat for the Rhodesian Crocodile.
