The M67 grenade is a fragmentation hand grenade used by the United States military. The M67 is a further development of the M33 grenade, itself a replacement for the M26-series grenades used during the Korean and Vietnam Wars, and the older Mk 2 "pineapple" grenade used since World War I.

Overview
editThe M67 grenade has a spheroidal steel body that contains 6.5 oz (180 g) of composition B explosive. It uses the M213 pyrotechnic delay fuse. The M67 grenade weighs 14 oz (400 g) in total and has a safety clip to prevent the spoon on the grenade from being triggered in the event the safety pin is accidentally pulled. The safety pin prevents the safety lever, or "spoon" on the grenade from moving and releasing the spring-loaded striker which initiates the grenade's fuze assembly.[1]
The M67 is typically known as a "baseball" grenade because it is shaped like a ball that can be easily thrown.[2] According to the FY2021 US Army Justification, the average cost of a single M67 grenade is around 45 US dollars.[3]
The M67 can be thrown 35 meters (115 ft) from the standing position by the average male soldier.[4] Its fuze delays detonation between 4 and 5 seconds after the spoon is released. Steel fragments are formed by the grenade body fracturing and have an injury radius of 15 meters (49 ft) and a fatality radius of 5 meters (16 ft), though some fragments can travel as far as 230 meters (750 ft).[4]
Variants
editM33 fragmentation grenade
editThe M33 was the original successor to the M26 fragmentation grenade. It was essentially identical to the M67, but lacked the safety clip that is fitted to the safety lever of the M67.
M68 fragmentation grenade
editThis is a variant of the M67 fitted with the M217 impact fuze and a safety clip on the safety lever. This fuze has an electrical impact function which arms within 1 to 2 seconds and will detonate the grenade upon impact, and a back-up pyrotechnic delay function which will initiate the grenade after 3 to 7 seconds if the impact function fails. The M68 has the same specifications and markings as the M67 except it has a red-painted fuze and lever to indicate it has an impact fuze.
M33A1 and M59 fragmentation grenades
editPredecessors to the M68, these impact-fuzed grenades used the M33 grenade body fitted with the M217 impact fuze, without a safety clip on the safety lever, and are marked similarly to the M68.
M69 practice grenade
editThe M69 grenade is used for grenade training to safely simulate the M67 grenade. The fuze screws into the body, and is replaceable after use. The simulator produces a report and a small puff of white smoke when employed.
The M69 has a blue-painted lever and a blue body with white markings. This is to indicate that it is a safe practice grenade rather than a live fragmentation grenade like the M33 or M67.
