This unit can trace its lineage back to the unit of the same name in the United States Marine Corps. Established in August 2003 at Marine Corps Air Station New River, this squadron was responsible for testing the MV-22B Osprey multi-mission tiltrotor aircraft, and all future aircraft of the type. VMX-22 is the first modern-day military unit to be featured in the Halo universe, though many other real-world units appear in Halo: Reach.
VMX-22 is part of the deleted material from the Halo games. During the development process, the developers are forced to remove some content from the final product. As such, many aspects of the games, such as vehicles, gameplay, and story elements, were not included in the finalized versions.
