I'd love to see some more Vietnam poses for the Americans, especially with an M60 gunner firing from the prone position, instead of from a tripod, as most other MG sections are arrayed. An assistant to feed the belted ammo would be nice, but isn't absolutely required.
A guy going "Rambo", and firing from the hip while standing would be useful too.
These can serve double duty, for both Vietnam, and the Cold War, European theater in the Summer.
