Looks like a Panzer 38(t) of 7th Panzer Division. I assume it's in Russia since that marking was used after '41 ^
EDIT:
(Probably) members of the 2nd Armored Division near St Lo France, 1944 juding by the camouflage (and Google
). It
looks like there are 3 different guns in the photo. From left to right; M1 Garand, M1 Carbine, and an M1903 Springfield with an M1 Grenade Launcher.
Actually, this 2nd image confirms it as a Springfield
seems to be the same group.
