The M67 grenade is a fragmentation hand grenade used by the US armed forces and Canadian forces - where it is referred to as the
C13. The M67 is a replacement for the M61 grenade used during Vietnam and the older MK2 "pineapple" grenade used since World
War II.

The M67 can be thrown about 40 meters by the average soldier. It has a 3 to 5 second fuse that ignites explosives packed inside a
round body. Shrapnel is provided by the grenade casing, and produces a casualty radius of 15 meters, with a fatality radius of 5
meters, though some fragments can disperse as far out as 230 meters. Its effectiveness is not just its blast radius, which measures
approximately 45 feet, but shrapnel that embeds itself into objects and people up to 700 feet away from the blast.[1] Three steps must
be taken to activate the grenade: the user first removes a "thumb clip" safety--many troops prefer to do this before initially stowing the
grenade, so as to reduce the time necessary to deploy it. Second, the user places the "spoon" lever between his thumb and forefinger
with a firm grip and pulls the pin. The grenade is not armed at this point and in fact the pin could be re-inserted to make a safe
weapon. Upon throwing (or dropping, as the case may be), the safety lever (which is under spring tension but held in place by the pin)
jettisons itself and simultaneously releases an internal plunger, which triggers the chemical fuse and detonates the weapon.
