Supervisor helmet

The Supervisor Helmet is a piece of headwear worn by raiders in the Fallout 3 DLC The Pitt.

Location
It can be found in several areas, such as on a raider positioned outside where Ashur usually stands (it can be aquired from him through killing him or Reverse-Pickpocketing better equipment).

It may also just be looted from the hostile Pitt Raiders killed before entering Downtown (or the ones in the arena fights), or even bought from Friday, a vendor in the Downtown section of the Pitt. She will sell you the Supervisor Helmet for about 70 caps (but in poor condition).

In the xbox version simply reload when you first exit the tunnel that leads to the pitt untill you see the hostile raiders whereing the Supervisor Helmet and do this for each new zone that you walk into for the first time in the pitt and if done correctly you should leave the pitt with five or more of this helmet type.
