Anaconda surface-to-air missile

The  Anaconda Surface-to-Air Missile is a type of anti-aircraft ordnance used by the UNSC.

These missiles are only mentioned once in the Halo series, during the book Halo: First Strike where the SPARTANS of Red Team recover a crate marked HIGHCOM Armory Omega during the Battle of Reach that contained six Anaconda Surface to Air Missiles and a pair of Fury Tactical Nukes; as far as we know the missiles were never used according to the book.
