Sentry Battle

Sentry Battle is the twenty-third track on Volume 1 of the Halo 5: Guardians Original Soundtrack. It is used in the level Evacuation, during the final wave on the Meridian space elevator against three Promethean Knights. The final portion also occasionally plays after losing a Warzone match.

It makes a return in Halo: Fireteam Raven with it's appearance in Escape, the first mission, the length of 0:00 to 2:09 being mainly played while the length of 2:09 to 3:40 is played during the space battle portion, and while the final portion is played during the second portion of the fifth mission, Raven Down.
