- "Alpha, this is Delta, we have visual on your position."
"We'd like to have your ammo on our position right now!"
"Roger that, sit tight."

Alpha Squad, or Alpha team, was a squad of Gears in the Coalition of Ordered Governments army who were assigned to deploy the Sonic Resonator. This device was intended to give out a sonic pulse that would map the Locust tunnels so that the data could be used for the Lightmass Bomb. However, it malfunctioned and the data was incomplete. The squad's status was been disbanded, since most of the members were killed, while the surviving two were reassigned to Delta Squad.
Delta Squad was assigned to find Alpha and radio for evac by King Raven helicopters. Delta Squad stumbled across a group of 3 dead COG soldiers, originally thought to be Alpha, outside the House of Sovereigns. Further into the House of Sovereigns, Delta met up with Cole, who was single-handedly holding off a group of Drones. Due to the loss of Anthony Carmine, Cole joined with Delta Squad to take his place and help rescue Alpha. After killing several Seeders, Alpha established communication with Delta, notifying them of Troika machineguns on top of the House of Sovereigns that were pinning them down outside the Tomb of the Unknowns. The surviving members then joined Delta after they were rescued.
