The Anvil-II Air-to-Surface Missiles, sometimes referred to as ASM's, are normally mounted via rocket pods on Pelican dropships or SkyHawk atmospheric jump-jets for clearing ground targets and drop zones of enemies.
This missile is used multiple times in the Halo games, used by pelican dropships to attack the Scarab at the end of Metropolis. It is used again by Pelicans in the Quarantine Zone, when a Flood-controlled Pelican flies past and shoots down some Sentinel Majors and hits the one Enforcer that is there. It is also on the second Pelican that shows up at the start of the level Delta Halo, though this dropship only fires very rarely. It is also used at the end of Sierra 117 in Halo 3, to clear out the ending area and allow the Pelican to land and give the player evac to the next level.
