Departure/Sniper Alley

Sniper Alley is the second chapter of Episode 1 in Spartan Ops.

Trivia
Sniper Alley is the nickname of an infamous section of the level Outskirts in Halo 2, in which Jackal snipers can kill the Master Chief almost instantly. The location became particularly disparaged when played on the Legendary difficulty, as the snipers can kill the Master Chief with even a grazing shot to the foot.
