FRAG GRENADE[]
M75 frag grenade. The explosion produces a large amount of shrapnel that causes heavy damage within a certain radius. Very effective grenade, can be used to force enemies out of their location, it's often found on marauders, and you'll easily be able to obtain it from them, it can also be bought at Heidi's store and the black market, but you should probably just get a lot of them from marauders
