Initially leaked in 2008, this is one of the rare videos that shows the 1st Special Forces Operational Detachment-Delta (1st SFOD-D, Delta Force, CAG) in action. Delta Force training and operations video was supposed to be some private club recruiting video. The video features music from Beastie Boys, Kiss, and Billy Squire.
So far, it is probably the only video of the United States’ most secretive special operations unit. It is the only unit which existence was officially never confirmed. It is assumed that they are considered as Tier 1 units operating under Joint Special Operations Command (JSOC).
