The 39th Reconnaissance unit served as a ground assault force within the Imperial Army and saw action during the Battle of Endor. Members of the 39th Recon, specifically the scout troopers, utilized 74-Z speeder bikes both for scouting missions and for swift movement across battlefields. Moreover, the unit possessed a number of AT-ST reconnaissance walkers, which they employed in quick attack maneuvers. While the 27th Elite Recon had more precise speeder bike squadrons, the 39th Recon's AT-ST component possessed a greater offensive capability.
