- "I don't understand. Why did these troopers attack us?"
- ―Dogma, to Captain CT-7567 "Rex"
During the Battle of Umbara of the Clone Wars, platoon leader Waxer of the 212th Attack Battalion was in command of a platoon. During the Grand Army of the Republic's campaign on Umbara, Waxer's platoon received information from Jedi General Pong Krell that the Umbarans had attacked a clone unit and were disguised with their armor and equipment.
Unknown to Waxer however, General Krell gave the same information to Clone Captain CT-7567 Rex of the 501st Legion, sending both units towards a confrontation. In the ensuing friendly fire incident that resulted in heavy casualties on both units, Waxer was fatally injured, and informed Rex of what Krell had told him, before dying of his wounds.
The surviving clone troopers of the platoon joined members of the 501st Legion to arrest General Krell for treason against the Galactic Republic, eventually apprehending him and executing him. By the time the incident was over, at least two troopers of the platoon survived.
