The A-74 Sylver Vertical Missile Launcher is one of the Vulture's main armaments, along with the four autocannons it mounts. As the name implies, it fires warheads vertically, in order to make them fall on hostile ground units, inflicting devastating damage. This launcher normally mounts Air-to-Surface Missiles. This weapon can be used as a unit ability in Halo Wars by pressing "Y" on the control pad, activating a "Missile Barrage", which can be upgraded for even more power.
