The M32 Grenade Launcher Module (GLM) is the U.S. military’s designation for a semi-automatic, shoulder-fired six-shot grenade launcher capable of firing 40mm grenades. It’s been in use by U.S. military forces since 2009. The M320 uses a High-Low Propulsion System and can be used in two ways. It can be attached to the M16 assault rifle, M4 carbine, or other rifles, attaching under the barrel forward of the magazine, or it can be used dismounted with a stock attached as a stand-alone model. The Day/Night Sight allows the grenadier to effectively engage the enemy in the dark.
In this footage, U.S. Marines with various major subordinate commands in III Marine Expeditionary Force (MEF) conduct live-fire training with the M32A1 multi-shot grenade launchers on Camp Hansen, Okinawa, Japan. A more reliable, ergonomic, accurate, and safer model than the grenade launcher modules, the M32A1 is a seriously powerful and lethal weapon at the services of U.S. forces.
