Behind the scenesEdit
AT-PTs debuted in the Legends novel Dark Force Rising, the second installment to The Thrawn Trilogy. Within the Legends continuity, "AT-PT" was the abbreviation for "All Terrain Personal Transport," but it is unknown if this is also true for the new continuity. The first canonical appearance of the AT-PT was in the 2014 mobile game Star Wars: Galactic Defense.
