Type-57 Troop Carrier

An unidentified Spirit model appears in Halo 5: Guardians. It appears to be in improved version of the T-25 Spirit, put into use in the Sangheili Civil War. It retains the tuning fork shape, but has longer prongs, and instead of large doors which open to expose the entire troop bay, each seat seems to have an individual door which opens independently of the others (although in gameplay, they open in sequence).
