This camouflage poncho was worn by Snafu in episode 9. It is screen matched. All camouflage markings match up to what is on screen.This poncho appears to have been used in the entire episode. Its shown as in the pictures below when they are digging foxholes and the ammo gets wet. To when Hamm gets killed. The production company made sure that the uniforms as well as this poncho was true to period. This poncho has USMC stamped inside along with Jan 12 1942. This is probably WW2 USMC surplus. The inside of the poncho is also very dirty with dried mud from production use.
