The D77H-TCI Pelican is an extremely versatile craft used primarily for transportation of personnel and equipment by the UNSC. Standard armament consists of one class-three externally powered projectile weapon at the fore of the vehicle and one class-one gas operated projectile weapon mounted at the rear in the extended crew area. More heavily armed versions exist.

NOTE: Prominent mention is made here of the Pelican's armament, which is interesting. Pelicans in Halo 1 had no visible armament at all. In Halo 2, we did see chainguns mounted on Pelicans, but they were rarely used except in cutscenes, and never usable by the player, who takes only one Pelican ride in the game, and that one ends in a crash.
