The GIGN (Groupe d'Intervention de la Gendarmerie Nationale) and DGSE (Direction Générale de la Sécurité Extérieure) are the French security services featured in Grand Theft Auto: Vice City. GIGN is a military special forces unit, comparable to the British SAS, while DGSE is an intelligence agency analogous to the American CIA. The "GIGN" name is derived from internal files of GTA Vice City.
