The Ox was designed after the Second Tiberium War to replace the aging Orca Carryall and provide air transport for infantry. It features tandem seating with the pilot in back and co-pilot in front similar to the attack helicopters of the 20th century. It came into use shortly after the Firestorm Crisis. The craft is equipped with powerful VTOL engines which, coupled with an aerodynamic frame, give it the ability to fly at high speeds and deliver ordnance to the battlefield in minutes. It also has a refueling probe at the front to extend its range.
