Halo Reach - UNSC Army Infantryman (Standing)


Since 2163






Garrison and defense





The UNSC Army is a branch of the UNSCDF primarily responsible for land-based military operations.[1] They launch offensive operations from land bases against land-based targets and are used in capturing and establishing control over UNSC-held territory. The UNSC Army frequently patrols colony planets.[1]


Human-Covenant war

In 2542, the Covenant found Alluvion. It would be the Army who would try to fend them off. However, the Covenant would overwhelm them and the planet would be glassed.[2]

During the Battle of Actium, Colonel Akono Menteith and the 53rd Armored Division defended the planet against a Covenant invasion force, ultimately resulting in all 12,000 Army soldiers being annihilated and the planet glassed.

On April 22, 2552, the Covenant assaulted Fumirole.[3] The Army and Noble Team would counter.[4]

Assault on Epsilon Eridani

Fall of Reach

When the Visegrád Relay went down, 3 Charlie was sent to investigate first, right before Noble Team.[5][6] The Army would also be the first responders when Sword Base would come under attack. Noble Team would provide support towards the end of the battle.[7] Noble Team would discover the Fleet of Valiant Prudence,[8] and as part of WINTER CONTINGENCY, the Army would counter where ever the Covenant was.[9] Operation: UPPER CUT would be executed by Noble Team while supported by the Army.[10] New Alexandria would be evacuated[11] and battled over by elements of the Army.[12] Noble Team would destroy Sword Base[13] and carry the package to Aszod. It would be SPARTAN-B312 who would defend the UNSC Pillar of Autumn before it left Reach.[14] Army forces would help defend ODG Facility A-412.[15]

Battle for Tribute
Main article: Battle of Tribute

At some point during the battle, the Army fought back against the Covenant on Tribute.[16][notes 1]

Attack on Sol

During the Battle of Earth, an Army unit of 20 troopers tried to aid Marine forces in New Mombasa and were annihilated in the attempt.[17]

During the Battle of Mare Erythraeum on MarsColonel James Ackerson led an unknown number of Army forces against the Brute commander Lepidus and his army.[18][notes 2] 


The UNSC Army uses different equipment and weaponry from the Marines, such as the M6J Carbine, the MA37 Assault Rifle, and the M392 DMR.[19]

All active duty soldiers of the UNSC Army wear the UNSC Army Battle Dress Uniform.

The UNSC Army utilizes the UH-144 Falcon, the M12 LRV, the M12R, the M12G1, the M831 TT, and the M808 MBT.






  • Some female army soldiers have hair descending down from their helmets, as opposed to the Marines, where all female Marines seem to have crew cuts.
  • The UNSC Army makes its in-game debut in Halo: Reach, in which UNSC Army soldiers, Marines, and ODSTs have their own service tags showing their name and rank. Some of them are named after Bungie and Rooster Teeth employees.
  • The UNSC Army is never mentioned and is not present during the Hillside Memorials dedication in Halo 3.


Concept Art



  1. As Gabriel Thorne was in the Army, it is most likely that the Army fought here.
  2. Considering that James Ackerson was an Army Colonel, the UNSC most likely used Army forces during the Battle of Mare Erythraeum.
