In an explosive, pyrotechnic device, or military munition, a fuse is the part of the device that initiates function. In common usage, the word fuse is used indiscriminately. However, when being specific, the term fuse describes a simple pyrotechnic initiating device, like the cord on a firecracker whereas the term fuze is used when referring to a more sophisticated ignition device incorporating mechanical and/or electronic components, such as a proximity fuze for an M107 artillery shell, magnetic or acoustic fuze on a sea mine, spring-loaded grenade fuze, pencil detonator, or anti-handling device.
The RGD-5 is a post–World War II Soviet anti-personnel fragmentation grenade, designed in the early 1950s. The RGD-5 was accepted into service with the Soviet Army in 1954. It was widely exported, and is still in service with many armies in the Middle East and the former Soviet bloc.
RKG-3 is a series of Soviet anti-tank hand grenades. It superseded the RPG-43, RPG-40 and RPG-6 series, entering service in 1950. It was widely used in the 1973 Arab–Israeli War and remained a common weapon into the 2000s and early 2010s, being favoured by Iraqi insurgents during the American-led occupation. Modified versions of the RKG-3 series have also emerged in the Russian invasion of Ukraine.
The Mk 2 grenade, also nicknamed the Pineapple is a fragmentation-type anti-personnel hand grenade introduced by the U.S. armed forces in 1918. It was the standard issue anti-personnel grenade used during World War II, and also saw limited service in later conflicts, including the Korean War and Vietnam War. Replacing the failed Mk 1 grenade of 1917, it was standardized in 1920 as the Mk II, and redesignated the Mk 2 on April 2, 1945.
The RGO hand grenade is a defensive Soviet fragmentation hand grenade. It consists of a double layered steel pre-fragmented body. It is very similar to the single-layered offensive aluminium-bodied RGN hand grenade. It uses the UDZS dual action fuze, which has both impact and time delay functions. The impact fuze arms after a pyrotechnic delay of 1 to 1.8 seconds. If the impact fuze has not triggered the grenade after 3.2 to 4.2 seconds a second pyrotechnic delay triggers the grenade. The fragments produced by the grenade generate a lethal radius of between 6 metres (20 ft) and 20 metres (66 ft), with the safety radius being 100 metres (330 ft).
The RGN hand grenade is an offensive Soviet blast hand grenade. It consists of a smooth spherical aluminium body, internally scored to generate fragments upon detonation. Externally, the RGN is similar to the RGO hand grenade. The UDZS fuze has both impact and time delay functions, the impact fuze arms after a pyrotechnic delay of 1 to 1.8 seconds. If the grenade strikes an object after this time a spherical lead shot filled impact weight will trigger detonation. If the grenade has not struck anything after 3.5 to 4 seconds the second pyrotechnic delay will detonate the grenade.
The Soviet RGD-33 is an anti-personnel fragmentation stick grenade developed in 1933.
The M26 is a fragmentation hand grenade developed by the United States military. It entered service around 1952 and was used in combat during the Korean War. Its distinct lemon shape led it to being nicknamed the "lemon grenade".
The military of the United States has used many different types of hand grenades since its foundation.
The V40 fragmentation grenade was manufactured in the Netherlands, and was in service in the Canadian Forces and the US Armed Forces.
The MK3 hand grenade is a cylindrical concussion grenade designed to produce casualties during close combat while minimizing danger to friendly personnel exposed in the open owing to minimal fragmentation. There is a secondary fragmentation hazard though from rocks, gravel, wood splinters, glass, etc. The grenade is also used for concussion effects in enclosed areas, for blasting, or for demolition tasks. The shock waves (overpressure) produced by this grenade when used in enclosed areas are greater than those produced by the fragmentation grenade. It is, therefore, very effective used in an offensive role against enemy soldiers located in bunkers, buildings, and fortified areas. It is commonly known as the "concussion" or "demo" grenade.
A tripflare is a device used by military forces to secure an area and to guard against infiltration. It consists of tripwire around the area, linked to one or more flares. When the tripwire is triggered, as by someone unsuspectingly disturbing it, the flare is activated and begins burning. The light from the flare simultaneously warns that the perimeter may have been breached and also gives light for investigating. In defensive operations, tripflares are usually placed in predetermined kill zones with machine guns sighted on them.
The HG 85 is a round fragmentation hand grenade designed for the Swiss Armed Forces, and is still produced by RUAG Ammotec in Switzerland. HG 85 is the internal designation of the Swiss Army and replaced the HG 43 from World War II.
The F1 grenade is manufactured by Thales Australia exclusively for the Australian Defence Force as a primary defensive anti-personnel hand grenade.
In military munitions, a fuze is the part of the device that initiates function. In some applications, such as torpedoes, a fuze may be identified by function as the exploder. The relative complexity of even the earliest fuze designs can be seen in cutaway diagrams.
A grenade is an explosive weapon typically thrown by hand, but can also refer to a shell shot from the muzzle of a rifle or a grenade launcher. A modern hand grenade generally consists of an explosive charge ("filler"), a detonator mechanism, an internal striker to trigger the detonator, an arming safety secured by a transport safety. The user removes the transport safety before throwing, and once the grenade leaves the hand the arming safety gets released, allowing the striker to trigger a primer that ignites a fuze, which burns down to the detonator and explodes the main charge.
The Dilagrama m/65 is a device employed by the Portuguese Army that fits G3 Automatic Rifles allowing them to launch defensive Type m/63 hand grenades further than they can be thrown by hand.
The Mk 1 grenade is a fragmentation hand grenade used by American forces during World War I. According to its designers, it was to be the "simplest", yet most "fool-proof", grenade ever made. However, some major problems appeared when the grenade was used in the field. It was retired from service before the war ended, replaced in 1918 with the improved Mk 2 grenade used through World War II.
The M1 grenade projection adapter was an expedient rifle grenade used by the American military in World War II, Korea, and Vietnam. It consisted of an add-on 22 mm (0.87 in) stabilizer tube and fins that converted a hand-grenade into a rifle grenade. It supplanted the M17 rifle grenade, and was eventually made obsolete by the 40 mm M79 grenade launcher.
The SFG 87 is a defensive fragmentation hand grenade created in Singapore. It is one of the grenades used for infantry divisions of the Singapore Armed Forces. The grenades are produced mainly by Singaporean weapons manufacturer ST Kinetics. It has been mass-produced since 1987, replacing the older SFG 82 and SFG 75 variants.
