The Syrian Free Army (SFA, Arabic: جيش سوريا الحرة), previously known as the Revolutionary Commando Army (RCA, Arabic: جيش مغاوير الثورة), and the New Syrian Army (NSA, Arabic: جيش سوريا الجديد), was a United States Army–trained opposition faction in southeast Syria. It was hosted at the US military's al-Tanf base and is now part of the Syrian Ministry of Interior.
Founded as an expansion of the Authenticity and Development Front by Syrian Arab Army defectors and other rebels during the Syrian civil war on 20 May 2015, the New Syrian Army sought to expel the Islamic State from southeastern Syria. In December 2016, the New Syrian Army dissolved, and the remnants of the group formed the Revolutionary Commando Army.
