3 Charlie

3 Charlie was a UNSC Army fireteam stationed on Reach in 2552.

Operational history
On July 23, 2552, 3 Charlie was on patrol in the Longhorn Valley. After contact with the comm relay hub in Visegrad was lost before the Covenant invasion, 3 Charlie was sent in to investigate the suspected Insurrectionist activity by Colonel Urban Holland, along with other Army fireteams. 3 Charlie was presumably eliminated by the vanguard Covenant invasion force that had sabotaged the relay.
