VN010-KC “Blooper” M79 Grenade Launcher
The M79 Grenade Launcher first entered service with the U.S. Forces in 1961. Vietnam was its baptism of fire. It could launch grenades farther and more accurately than its predecessors and was much used at squad and platoon level.
This Marine sits on his butt as he aims and fires. The M79 got its “Blooper” nickname from the sound it made as it fired.
