M319 IGL

The M319 Individual Grenade Launcher, more formally known as the Individual Grenade Launcher, Caliber 40mm, M319, is a single-shot, break-action explosives launcher used by the United Nations Space Command, specifically the UNSC Army. Due to its simplicity, ruggedness, and firepower, it has been a mainstay weapon in the UNSC Army since its adoption in 2263, and has seen action in several armed conflicts during nearly three centuries of use.


Use versatility

The grenade launcher has two firing modes. The first launches a single grenade: after hitting a surface, the grenade detonates on impact with an opponent or after the time of a frag grenade’s detonation, in which case the grenade will explode after bouncing off the ground once. The second firing mode shoots a grenade that explodes when the soldier wishes. This is performed by holding down the trigger, which fires the grenade but merely primes it; it will only explode after the trigger is released.

The weapon utilizes a break-action breech-loading system: after firing one round, the weapon must be reloaded, like many twentieth century shotguns.

Tracking System

The IGL also has a tracking function which is useful when trying to target enemy vehicles that are fleeing; as long as the enemy is in range, and the targeting reticule is red (which is the indication of in-range enemies), using either firing modes will ensure in a perfect shot as long as the cursor remains on the enemy at all times the grenade will track the target.

EMP Function

Also, it can be loaded with a form of EMP grenade (M58 EMP), that can temporarily disable vehicles, but only when used in the manual detonation mode.


The Individual Grenade Launcher is a weapon of potentially high lethality, even in the hands of unskilled soldiers it can be effective; however, it is believed to be more difficult to use than a Rocket Launcher, yet the two weapons retain the same aspects of splash damage that is capable of eliminating multiple foes. In a skilled soldier’s hands, the Launcher can be a perfect asset in crowd control. As the IGL basically delivers modified frag grenades, the grenades themselves are similar to the throw-able Fragmentation Grenade in both dynamics of physics as well as properties of explosive splash damage that can be spread to a single enemy or a group of enemies.
