Warthog : Officially designated the M12 Light Reconnaissance Vehicle, this jeep forms the backbone of the human ground forces. It is fast, agile, and armed with a large chaingun. The Warthog uses Halo's animation system to feature true 4-wheel steering and deformable suspension. Three players can ride in it: one driving, one in the passenger seat firing a handheld weapon, and one manning the gun. The Chaingun mounted behind, the M41 light anti-aircraft gun is (according to the Halo manual) a "three-barreled, electric-powered linkless, drum-fed weapon." It fires roughly 500 rounds per minute.
Scorpion : Officially designated the M808B Sorpion Main Battle Tank, this huge tank was nicknamed the BAT (Big Ass Tank) (before its true name was discovered), and it fits. It is armed with a large cannon on a swiveling turret and a machine gun as well. Its tracks tilt to follow the terrain it is driving over. There is space for up to four characters to ride on its track pods, as well as a hatch for the driver to climb inside it.
Pelican : This dropship is used for insertion and extraction of troops or equipment in the field. In the game, the player does not actually drive the Pelican, but is instead ferried around the Halo between missions. It is capable of VTOL with its swiveling lift jets, and kicks up dust when it hovers. Most of the Pelicans in the game have distinct names and personalities.
Banshee: A Covenant aircraft. When parked its roof is almost vertical; it folds down over the pilot when in use. Its weapons are stored in the two large pods on the front; it can be seen firing briefly at the end of the third BTV movie. It carries 1 person, who lies prone under the windshield with his legs sticking out the back. The most striking feature of the Banshee is the gorgeous twin contrail it leaves in the air behind it. It is armed with twin plasma cannons and a Fuel Rod Gun.
Ghost: This one-person Covenant craft behaves like an airborne motorcycle. It is armed with twin plasma cannons.
Wraith: This covenant mortar tank attacks by lobbing huge balls of plasma high into the air. It hovers above the ground, and is quite maneuverable.
Covenant Dropship: This is the Covenant transport vehicle. Troops ride in the two large pods, and vehicles can be carried by a sort of forcefield in the middle. The vehicle is flying to the left in this image.
