UNSC Army

The UNSC Army  is a branch of the UNSC Defense Forces primarily responsible for land-based military operations.

Background
Little is known about the UNSC Army. This may be due to the fact that the Army is a land based fighting force, and thus little of the Army is assigned to naval battle ships, with the exception of transport by landing ships for planetary assaults.

The Army is a land-based fighting force. It is just as efficient as the Marines but are used in more conventional roles. The UNSC may have needed a faster, more mobile fighting force like the Marines to hunt down the rebels. They also may have different weapons such as the Rhino battle tank. It is possible that the UNSC Army is only used in planetary defense are not seen as Halo takes place on naval ships and unidentified rings.

 * The only known confirmed member of the UNSC Army is Colonel James Ackerson, an intelligence officer who was once an infantryman. He is seen in an Army dress uniform.
 * A joke among members of the Halo community is that the UNSC actually has two Armies, Red and Blue. This is a reference to Red vs. Blue, a popular Halo machinima.
 * The UNSC Army has its own variant of the M6; the M6J Carbine.
