M460 automatic grenade launcher

The M460 Automatic Grenade Launcher, (abbreviated M460 AGL), is a United Nations Space Command grenade launcher that is mounted on the UH-144A Falcon transport/utility helicopter. 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 aircraft-mounted grenade launchers.
 * Despite its name, there is no way to fire the weapon automatically 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.
