The figures are predominantly plastic WW2 figures from Wargames Factory, but with arms, heads, weapons and kit all mixed around. The idea was to represent a well trained but spottily-supplied standing army for a frontier world contested by two other alien powers in the endless war between the Nathi and Silmn in The Worlds In My Head.
Painting was as follows:
-brown ink all over
-red ink on the helmets and kit
-black ink on everything but the trousers
-black on weapons and boots
-light drybrush white on the black bits.
