M203 Grenade Launcher

One of the most powerful weapons available to U.S. Army and Marine Corps infantry is a grenade launcher designed to fit underneath the M16 rifle.


The M203 grenade launcher gave soldiers unprecedented grenade range in a compact, durable package. The weapon, introduced in the waning days of the Vietnam War, is only now being replaced by a new, similar one. Credit : NC Military
