C13

C13 Fragmentation Grenade
The C13 fragmentation hand grenade is the Canadian designation for the United States’ M67 grenade. A replacement hand grenade was needed for the outdated M26A2 used since the Korean War and Mk2 “Pineapple” grenade that had been in use since World War II.

The C13 contains six point five (6.5) ounces of Composition B, a mixture of Research Department Explosive (RDX) and Trinitrotoluene (TNT), and is detonated by the M213 fuse, which was specifically designed for this grenade, between three and four seconds after releasing the spoon. When throwing a grenade, always yell “Frag out!” to alert friendlies nearby. Do not yell “Grenade!” as that term is used to warn of an incoming or fumbled grenade that is a threat to you or your unit.
