Rifle grenades

Also known as
  • Rifle grenade
  • Rifle-launched grenade
  • Cup-discharge rifle grenade
  • Spigot rifle grenade
  • 22 mm rifle grenade
  • Bullet-trap rifle grenade
  • Shoot-through rifle grenade
  • ENERGA rifle grenade
  • No. 94 Energa
  • M31 HEAT rifle grenade

Rifle grenades are a broad family of grenades projected from service rifles by rod, cup, spigot, muzzle-device, bullet-trap, or shoot-through launch methods. World War I examples extended infantry grenade reach with explosive, smoke, signal, message, and emerging anti-tank payloads, while postwar HEAT designs such as the British No. 94 Energa and U.S. M31 used shaped charges for short-range anti-armor fire. The cataloged conflict record spans rifle-launched use, recovered ammunition, and modern reuse of rifle-grenade munitions as drone payloads in Myanmar and Ukraine.

Role in Conflicts

Side
North Vietnam and Viet Cong

A U.S. Marine Corps history reproduces the Medal of Honor citation for Corporal Larry Smedley, describing Viet Cong and North Vietnamese Army troops near Happy Valley in December 1967 and an enemy rifle grenade exploding nearby during the action.

Side
Philippine government forcesIS-aligned militants

Philippine Joint Task Force marines, army, and police tactical units were described using rifle-grenade fire with mortars and small arms while advancing through Marawi's built-up districts; a Philippine News Agency report separately documented recovered rifle grenades in the main battle area believed to have come from Maute-group materiel.

Side
People's Defense Forces and ethnic armed organizations

Myanmar reporting and regional analysis described local defence or People's Defense Force units dropping M9 rifle grenades from commercial drones onto junta troops or checkpoints in 2022, using the rifle-grenade munition as an aerial payload rather than a rifle-launched round.

Specifications

Launch interfaces
Early rifle grenades used rods inserted into the barrel or cup dischargers; postwar and modern examples include dedicated projectors, spigot launchers, and standard 22 mm muzzle interfaces.
Propulsion methods
Older systems commonly required special blank or ballistite rifle-grenade cartridges, while shoot-through and bullet-trap designs allow selected grenades to be launched with ball ammunition.
Typical payload roles
High explosive, fragmentation, smoke, signal/message, illumination, incendiary, and HEAT anti-armor payloads depending on the specific grenade model.
Modern bullet-trap example
Instalaza's FTV is a 36 mm rifle grenade for 5.56 mm rifles with a standard 22 mm muzzle, bullet-trap launch, 150 m point-target effective range, and 300 m maximum range.
Crew
One rifleman when rifle-launched; modern conflict evidence also includes rifle-grenade munitions repurposed as drone payloads.
Launch Method Families

Rifle grenades are grouped less by one manufacturer than by how the rifle launches them and what cartridge the firer must use.

Blank cartridge

Rodded, cup, and many postwar projector systems used special blank or ballistite cartridges, including the British No. 94 Energa.

Cup or spigot

Cup dischargers and spigot-style projectors let the grenade sit outside the bore, reducing the barrel wear associated with early rodded grenades.

Bullet trap

Modern bullet-trap grenades such as the Instalaza FTV are designed for standard ball ammunition and 22 mm muzzle interfaces.

Variants

Rifle grenades are best treated as a design family rather than a single model: the useful distinctions are launch interface, cartridge requirement, and payload role.

VariantConfigurationDesignation notes
Rodded rifle grenadesEarly barrel-insert launch format

World War I examples inserted a rod down the rifle barrel and used a special blank cartridge; later cup systems reduced rifle wear problems associated with rodded firing.

British training material identifies the Energa as the Anti-Tank Grenade No. 94, fired from a No. 4 rifle projector with a special .303-inch rifle-grenade cartridge.

Timeline

Rifle grenades Key Events

  1. Rifle grenades become a World War I infantry tool

    National WWI Museum material describes wartime rifle grenades carrying high explosive, smoke, signals, messages, and late-war anti-tank payloads.

    Sources: Grenades

  2. British cup-launched Mills adaptation replaces rodded wear problem

    Imperial War Museums notes that a spring 1918 No. 36 Mills grenade adaptation used a gas-check disc in a discharger cup and replaced rodded grenades that caused excessive rifle wear.

    Sources: Grenade, hand and rifle, No 36 M Mk 1 (Sectioned)

  3. British No. 94 Energa training manual issued

    War Office training material identified the Energa as an infantry section anti-tank weapon fired from a No. 4 rifle projector with a dedicated rifle-grenade cartridge.
