Imperial AT-ST. Heavy modification of the Rogue One official set (75153) with an all new cockpit/head with seating for two, all new drive section, new ball jointed upper/lower hip joints, new armament and redesigned leg detail. The roof still opens for interior access, the cockpit rotates at the "neck" joint, the knees are poseable and the hips have greatly increased range of motion using Bionicle joints. The chin cannons have a firing arc from +15 degress to -90. I used both the Bandai model kit and the Black Series 3.75" scaled toy for reference.
