The Tronanlak-class troop carrier was a troop shuttle based on the old KT-400 military droid carrier, it was used by both the Imperial Navy and Imperial Army, it was used to deliver troops to the surface of a planet during an invasion, an example of this was the Invasion of Hyaxnox. This shuttle could be found both on planet-side military bases (usually these were Imperial Army bases, but there were also Imperial Navy ground-based garrisons) or on troop transports of the Imperial Navy.
