Formally known as Imperial swamp troopers, mudtroopers are part of the Imperial Army, whose infantry is gradually being phased out in favor of stormtroopers. Mudtroopers wear partial armor, augmented with respiratory gear and sealed bodysuits for combat in unhealthy environments such as Mimban. Han Solo served as a corporal with the 224th Imperial Armored Division, a new incarnation of the Mud Jumpers of the Clone Wars.
