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 none of the Army is assigned to naval battle ships, with the exception of transport by landing ships for planetary assaults.

The Army it is a land fighting force. It is just as efficient a fighting force as the Marines and are use more in conventual battles. The UNSC needed a faster, a more mobile force like the Marines to hunt down elusive rebels and later they have a lot of the same weapons as marines.They also have different weapon like the rhino battle tank.
