The M67 Fragmentation Hand Grenade is used to supplement small arms fire against enemies in close combat. The grenade produces casualties by a high velocity projection of fragments in a uniform distribution pattern. The grenade body is a 2.5 inch diameter steel sphere which is designed to burst into numerous fragments when detonated. The grenade body contains approximately 5.5 ounces of Composition B explosive and is fitted with an M213 fuze which is a pyrotechnic delay detonating device. The M213 Fuze gives the Soldier 4.0 to 5.5 seconds of separation after release of the safety lever. The M213 Fuze is equipped with a steel safety pin and pull ring. The split end of the safety pin is duckbill shaped to prevent accidental removal and arming during shipping or handling. The pull ring is provided to facilitate easy removal of the safety pin. A second safety feature is the steel safety clip. The safety clip's purpose is to prevent the safety lever from moving in the event the safety pin is accidentally dislodd from the fuze. In addition to these safety features, a “Confidence Clip” was added to restrain the pull ring and reduce the likelihood of accidental removal.
The AN-M14 TH3 Incendiary Hand Grenade is used to destroy equipment or start fires; it can also damage, immobilize, or destroy vehicles, weapons systems, shelters and munitions. The grenade body is of thin sheet metal and is cylindrical in shape. It is filled with an incendiary mixture, Thermate-TH3 that burns from 30 to 45 seconds, generating heat to 4,000°F. The AN-M14 incendiary hand grenade employs the M201A1 fuze.
The M111 Offensive Grenade is the designated replacement for the Mk3A2 and provides the same performance envelope. It produces casualties during close combat while minimizing danger to friendly personnel. The grenade is also used when lethal fragments are not desired to reduce collateral damage.
