Sector Six
From Halopedia, the Halo wiki
Sector Six[1] was formerly a location on Earth.
Orbital Drop Shock Troopers Bravo-21 and Bravo-22 were ordered there during the Second Battle of Earth to get medical attention from a UNSC medic at that location. The ensuing battle, the Battle of Sector Six, met with heavy casualties on the behalf of both UNSC Marine forces and Jiralhanae forces. Bravo-21 was killed by a Cheiftain. Its coordinates were at 32°53′12″N, 69°27′48″E on Earth [2], and Sector Six was believed to be two miles east of Pawas, Afghanistan, a small town on Earth.
