Figure 15–9. Surface danger zone for M2/M4A1 Selectable Lightweight Attack Munition and M3 Demolition Attack Munition 15–14. Rifle Launched Entry Munition and Grenade, Rifle Entry Munition a. The Rifle Launched Entry Munition (RLEM)/Grenade Rifle Entry Munition (GREM) M100 is a lightweight, muzzle-launched, rifle grenade designed to break down a door and allow the entry into a building or enclosed area with minimum hazard to the operator. The RLEM/GREM is fired from the muzzle of a personal weapon (M16-series rifles and M4-series weapons). It has a bullet trap which allows the use of 5.56mm M855 ball and M856 tracer rounds. The RLEM/GREM is launched by firing a round to a distance of at least 15 m. It has a standoff rod that provides optimal distance for initiation of the explosive charge. A disk on the end of the standoff rod prevents penetration of the rod into the target. The warhead has a plastic cover which eliminates the explosive splashing toward the gunner. The pyrotechnic adapter keeps the explosive away from the tail section, preventing flyback of the tail toward the gunner. b. The GREM–Target Practice (GREM–TP) M101, is a reusable training device used to train personnel for the GREM. The GREM–TP is externally similar in shape and form to the GREM, but it is nonexplosive. M195 grenade cartridges are used for firing because there is no bullet trap. Each GREM–TP comes with five standoff rods. 199 DA PAM 385–63 • 16 April 2014
