Binh Xuyen Force (Vietnamese: Bộ đội Bình Xuyên, IPA: [ɓɨ̂n swiəŋ]), often linked to its infamous leader, General Lê Văn Viễn (a.k.a. "Bảy Viễn"), was an independent military force within the Vietnamese National Army whose leaders once had lived outside the law and had sided with the Việt Minh. During its heyday, Bình Xuyên funded itself with organized crime activities in Saigon while effectively battling Communist forces.
