Updated again 05/11/08 with Combat Desert Ops Flamethrower version! Same construction as the last ones. These are fun to make!
Updated with Combat 'stealth' variation. He's styled up like a Black Ops unit and was made from the top half of a SW Assassin Droid, MARS robot head, Commando Snake Eyes lower body/harness, and Xamont (or Tomax, heh) hands.
Here's one of my new GI Joe 25th Anniversary custom figures, C.O.M.B.A.T. upgraded from his original Sigma 6 custom fig in my archives. Combat was made from a Cobra soldier lower half, Star Wars Assassin droid upper half, MARS robot head, and various random parts. He can look around in all directions and had the shoulder laser replaced with a machinegun. The American Flag was hand painted on his shoulder.
