He was with a squad of clone troopers when two trident drills appeared and dispatched aqua droids commanded by Grievous, who ordered the machines to kill all the clones. The troopers immediately engaged Grievous's forces. While helping a wounded Clone Havoc spotted 99 giving troopers extra DC-15 rifles, and he immediately ordered 99 out of the fight. But while distracted, Havoc was shot in the shoulder, and received a lethal hit to the head seconds later. 99 then grabbed Havoc's standard clone backpack that was full of grenades, and quickly hurried off to find Echo and Fives.[3]
Havoc had blue markings on his experimental Phase II clone trooper armor with a rangefinder on the right side of his helmet. He wore a unique shoulder pauldron and had four blue squares that covered his chest and abdomen. He, Colt, and Blitz all wore the same specialized pauldron. Finally, he wore a kama with blue stripes. In combat, he wielded a DC-15A blaster rifle. During the Battle of Kamino, he used a standard Republic backpack.[3]
