First squad

First Squad was a United Nations Space Command Marine Corps military unit.

It was stationed in the Kenyan jungle of Africa, Earth during the Second Battle of Earth and was part of the Marine force that found SPARTAN-117 after his atmospheric landing. When SPARTAN-117 was revived, during the UNSC exfiltration operation from the jungle Sergeant Major Avery J. Johnson assumed command of First Squad, ordering them to deploy and move out as his scouts.

First Squad was presumably exfiltrated with Johnson via Pelican and taken prisoner by the Brutes in the subsequent interception of their dropship.
