Col. Kurtz-
I just gave the recessed areas a dark wash and a basecoat of MM Armor Sand, then just went with Flat Brown and Tan in no particular pattern; The real fun was the "chocolate chips"... Flat Black with White using an Exacto clamp base and magnifying glass with a really fine 10/0 sable hair brush. The faces were a Tan base drybrushed with a lighter topcoat... The thing that drove me batty was doing the eyes, teeth, helmet cover rank patch and shoulder insignias...
