Abandoned! (Into the Heart of Darkness 1)

Captain Marcus is angered by Admiral Winfield's decision to not attempt to liberate Earth, which he perceives as cowardice. After sending Able Squad (minus Weston and Takagi) on a secret mission to Mars as a way of getting rid of Marsh and other Winfield supporters, Marcus mutinies with the support of at least one other captain and most of the Resolute's security forces. The mutiny succeeds, with Winfield and his supporters (including Weston and Takagi) being locked in the brig. Able Squad reaches Mars, and the episode ends with them fleeing pursuing Neo e-frames.
