Combat sentry proto MK IV holotape

Combat sentry proto MK IV holotape is a holodisk in Fallout 4.

Location
It can be found on a terminal in the main building of the Robotics Disposal Ground. The holotape contains the remote control program for a prototype sentry bot. If the holotape is used on the Pip-boy when the player is in proximity to the sentry bot it will work, but too far away or on any terminal other than the one at the Robotics Disposal Ground, it will show an error and not do anything. Using the holotape's application on-site can send the Sentry Bot to a variety of military installations to kill any and all hostiles in the area.

Trivia

 * The perk Robotics Expert can be used to interact with the sentry bot once this holotape is used to activate it, with the exception to activation and deactivation.
