DCTA laser firearms protocol

DCTA Laser Firearms Protocol is a handbook on how to use the Laser Pistol.

The holotape is located in Farragut West Station. In the room with a locked cage door and ghouls there is a room if you face 180 degrees from the cage door. When you enter the room you will find a computer with options like opening the cage and releasing gas. Behind the desk is an average locked safe containing this note and a Laser Pistol.

The protocol is probably intended to be an introduction to the Laser Pistol and its ability to trigger an explosion by igniting gas, as this would be the first place where you can find one if you follow your father to GNR right away.
