Quadrant 4

Quadrant 4 was a region in the northern hemisphere of Harvest, where UNSC Hornets aerial reconnaissance, on orders from Professor Anders, observed a battalion-sized strength of Covenant. Sergeant John Force was sent on a reconnaissance patrol to determine the force strength and intent, but the Covenant presence had already moved north, into a Forerunner relic. It is likely that this patrol saved him from being present at the Covenant's destruction of Alpha Base.
