Combat inhibitor

All robots in Fallout 3 have a combat inhibitor.

Uses
Destroying this through combat, using the Robotics Expert Perk or by destroying it by any other means will cause the robot it belongs to to go into a killing frenzy and attack every entity it comes into contact with. This is not unlike destroying the Giant Ant's or Fire Ant's antennae and sending them into a frenzy, although much harder to accomplish since the Combat Inhibitor is located at the back of the robot's body.
