Brig

A brig is a jail aboard a ship. A person in the brig may also be referred to as "in hack" (Miniseries, "The Captain's Hand").

Battlestar Galactica has several brigs. One has at least two small cells with bunks. The other brig has one larger cell with no commodities for high-security prisoners.

In the episodes in which the brigs have made appearances, there is usually a Marine guard standing watch inside the room. In the high-security brig, there are usually around four.

After "Boomer" Valerii is revealed as a Cylon, Colonel Tigh orders the construction of a third reinforced brig, built for the specific purpose of containing captured Humanoid Cylons, who possess strength far greater than a human, for an extended period (Resistance).

The new Cylon brig is constructed with maximum security in mind; instead of having simple bars, its walls consist of metal grid screens welded tightly together, reinforced by composite plastics (a telephone is used to communicate between the inside and outside of the cell).

After being brought to Galactica, Caprica-Valerii is detained within the new Cylon brig. The virtual Number Six image that haunts Gaius Baltar falsely claims that Valerii's hybrid daughter will be born in this cell (Home, Part II).

Battlestar Pegasus has a more advanced brig than Galactica, with composite plastic walls instead of metal bars, and computer ID recognition cards required for entry.
