M460 automatic grenade launcher

The M460 Automatic Grenade Launcher (AGL), is a United Nations Space Command grenade launcher that is mounted on the UH-144A Falcon. The weapon has two firing modes which are similar to those of the M319 Individual Grenade Launcher. Tapping the trigger causes the weapon to fire a single grenade round that detonates on impact. Holding the trigger fires a grenade that will not detonate until the trigger is released. Grenades fired in this mode release an electromagnetic pulse on detonation; this EMP is capable of disabling most electronics, including those aboard vehicles and energy shielding emitters.

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.
 * Despite its name, the weapon is limited to semi-automatic fire in-game.
 * In the level New Alexandria, the second player in co-op receives a Falcon armed with an M460 AGL rather than the M247H Heavy Machine Gun that is used by most Falcons in-game.
 * When a grenade fired from the M460 AGL explodes, the weapon's display says "BOOM!". This also occurs with the M319 IGL.
 * 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.
