Sergeant John Forge is a veteran NCO with the UNSC Marine Corps. As a battle commander, his strategy strongly favors vehicle-orientated battle and focuses on slow-building strength, entrenchment and sustained growth.
Forge was a career soldier who served during the Human-Covenant War. Although his tactical ability and combat prowess were undoubted, his tendency towards insubordination prevented him from achieving a high rank. On the Shield World 0459 he gave his life to save the Spirit of Fire when he stayed behind to detonate the ship's translight engine to destroy a Covenant armada. His body was never recovered.
