The M60 is primarily designed to be fired from the U1 Grenade Launcher, although it can also double as a hand grenade. The cartridge consists of two main sections — a rimmed, separating base and a metal casing topped with a white plastic identifying cap. When fired from a U1, the base propels the casing from the grenade launcher's barrel. When the round impacts the white phosphorous spreads up to 15 meters, creating a rising smoke cloud and flame with a secondary incendiary effect against vegetation and material.[1]
