They were often used as assassins and were equipped with built-in blaster, explosive projectiles, and blades and spikes for close combat. The droids were 2.3 meters tall. They were designed for security and military duties, and were known to be determined and effective fighters. One drawback of the design was the hands, which required the droid to use specially designed weapons. It was also limited due to its large size, which could hinder its ability to move or use small objects.[1]
