A full battery of Imperial Army stormtroopers was stationed on the Mid Rim planet Mapuzo in 9 BBY. The battery maintained several facilities on Mapuzo, including an Imperial facility on the plains, a checkpoint, and a presence at a spaceport near a village. After Jedi Master Obi-Wan Kenobi was located on Mapuzo by the Inquisitorius, the Fourth Sister ordered the Imperial officers assigned to the Inquisitorius to mobilize their battalions and shut down every port.
