M460 automatic grenade launcher

The M460 automatic grenade launcher (AGL), is a 40mm grenade launcher utilised by the armed forces of the United Nations Space Command.

Design details
The M460 exhibits very similar operating principles to the M319 grenade launcher utilised by UNSC infantry personnel, including the utilisation of the same 40mm grenades such as the Mk110 MOD 2 HEDP and XM20 P EMP grenade - the latter of which can be used to create an electromagnetic pulse upon detonation. The weapon itself is bulky and consists of a belt feed into the launcher, allowing the operator to rapidly fire the grenades in question. The top of the weapon fits a small picatinny rail and an iron sight.

Like the M319, the M460 is equipped with a remote detonation system mounted on the side of the weapon, which can be used to delay the activation of the grenade's fuse - allowing the operator to remote-detonate the fired projectile when they deem necessary.

Usage
The M460 is typically employed as a vehicle-mounted weapon, most commonly deployed as a gunner mount on the UH-144A "Attack" Falcons, in place of the standard variant's use of the M247H machine gun. The D77-TC Pelican has a clamp in the rear cargo bay that allows for the instalment of a variety of weapons systems, with turret-mounted grenade launchers (presumably the M460) among them.

Halo: Reach
The M460 grenade launcher is primarily useable in the Halo: Reach campaign in two instances; the Falcon gunner section of Tip of the Spear, and on the level New Alexandria. By default, the Falcon spawned on New Alexandria equips dual machine guns, though a grenade launcher-equipped one will spawn in cooperative play. The grenade launcher-equipped Falcon was added to the Forge mode in the Thorage updates for Halo: The Master Chief Collection, allowing it to be used in multiplayer.

The M460 overall has near-identical performance to the standard Grenade Launcher weapon, though is capable of rapid semi-automatic fire instead of needing to reload after every shot. Grenades from the M460 will home in slightly on any target that the firing HUD is pointed at, as long as the target is close enough for the HUD to turn red. This can be useful during co-op playthroughs of New Alexandria to eliminate Banshees with ease.

Trivia
The M460 AGL is very similar in function and appearance to the modern Mk 19 grenade launcher, as both are automatic helicopter-mounted grenade launchers, though the Mk 19 can also be mounted on a variety of other vehicles, including HMMWV "Humvees" and river craft.
