Rustoleum Army Green rocks, But I have seen at meijers in the auto department, they had flat green which I swear is the same color as the chief's armor, I forget the brand or color name, but I took the can to the halo poster, same color, can was 5 dollars each, I'd say 2-3 cans will do the armor....plus 2-3 cans of base coat white/gray/black whichever you choose, I buy my base coats at Big lots for 1 dollar a can, works fine for me.
