Experimental Rho ID

The  (or R76-H3-0 chip, RHO Chip) is a chip card worn by Enclave Officers deployed to the RHO experiment.

The RHO Chip sends out a short range signal that will allow the wearer to freely wander the particular (and only this) camp under the protection of the provided armaments (usually Mark VI Turrets). The defense systems will only recognize the person in possession of the RHO Chip, and thus will attack every enemy of the Enclave. One of RHO Camps is located south-west of Canterbury Commons and north-west of Vault 108.

Effects Of The ID
If you have a high enough sneak (or a Stealth Boy), you can sneak up and pickpocket the id from the officer. The turrets will then become friendly to you, but will not attack the officer. It is unknown if they will defend you from threats outside the camp, such as animals, etc.
