This grenade supplements small arms fire in close combat scenarios. It causes casualties with a high-velocity projection of fragments in a uniform distribution pattern. The 63.5 mm diameter steel sphere contains 6.5 oz of highly explosive filler, and is fitted with a fuze that initiates the charge. It has a delay time of 4–5 seconds after the safety lever is released. The fragmentation gives the grenade a lethal radius of 5 m, causes casualties at up to 15 m, and disperses fragments as far away as 230 m.
