Unit B is a cell block in Oswald State Correctional Facility.
Unit Information Edit
The unit first appears in season 2. After the riot, all the prisoners in Emerald City were transferred to Unit B. It is a very large and populous cell block in Oz and during the show, many of the inmates have stayed there. Inmates that had to be transferred out of Emerald City, for whatever purpose, were transferred to Unit B. The Aryan Brotherhood's leader Vernon Schillinger was transferred to Unit B and it subsequently became the gang's turf. It can be assumed that during the show, the Supervising CO in Unit B is Andrea Phelan, although Sean Murphy was briefly the Supervising CO. It is never mentioned who the unit manager is; Tim McManus was the unit manager at one point, while Martin Querns ran Emerald City.
