The 1st Special Forces Operational Detachment–Delta (Delta Force / CAG), JSOC's Task Force Green, is the Army's primary counterterrorism, hostage-rescue, and direct-action unit. Founded by Charlie Beckwith, it participated in Eagle Claw and has executed high-value raids (e.g., the al-Baghdadi operation). Its existence and missions are documented; the alleged UAP crash-site role is unverified.
