The 2nd Parachute Chasseur Regiment (French: 2e Régiment de Chasseurs Parachutistes) or 2e RCP, is one of the most decorated French units of the Second World War, the only land unit awarded the red fourragère in that war, including six citations at the orders of the armed forces. The French Navy 1500-ton class submarine Casabianca also accumulated six citations at the orders of the armed forces and therefore its crewmen were entitled to wear the same fourragère. The unit was commonly referred to in the British Armed Forces as the 4th SAS.
