Combat inhibitor



All robots in Fallout 3 and Fallout: New Vegas and most robots in Fallout 4 and Fallout 76 have a combat inhibitor located on their back, while turrets have a targeting chip (ceiling-mounted turret) or lens (floor turret) underneath their gun barrel. Disabling the inhibitor will send the targeted robot into a frenzy.

Function
The combat inhibitor is a device that controls the machine's targeting parameters and allows a robot to differentiate between friends and foes. Combat inhibitors are very small and are usually located on the back of robots. In the event that the player character chooses to cripple the combat inhibitor by targeting it with V.A.T.S. or by accurate free-firing, the robot will go into a frenzied state and attack the closest target to it and continue to fight until it dies. The player character will be notified that the robot "has been frenzied" as if a limb was crippled on an enemy.
