Military prisons are used variously to house prisoners of war, unlawful combatants, those whose freedom is deemed a national security risk by the military or national authorities, and members of the military found guilty of a serious crime.
Militære fængsler bruges til at huse krigsfanger, ulovlige kombattanter, personer hvis frihed anses som en trussel mod den nationale sikkerhed, eller ansatte ved militæret fundet skyldig ved en krigsret i en alvorlig forbrydelse.
