This armour can be found in Old Olney which is located in the northeast section of the map. Set the difficulty to 'Very Easy' before you go there as the area is swarming with Death Claws. On the southern-most street of the town is a grate on the sidewalk which will open out from under you when you step on it forcing you to go through the sewers. Fight your way through the sewers until you find a Brotherhood of Steel Initiate who will be wearing the armour. The armour talks and will inject you with Med-X when your limbs are crippled. It does not come with a helmet.
