General Overview:
Transportation
The brig or holding cell is a type of prison on board a starship, space
station or planetary facility. These are heavily-guarded rooms that employ
either gates or force fields to keep those incarcerated segregated from the
general population of the vessel. These areas are used to contain criminals,
fugitives, and others who pose a security risk and must be detained. They
are also used as a means of punishment within the Starfleet ranks.
