Originally 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. A video of Delta Force training and operations was supposed to be some sort of private club recruiting video. The video featuring music from Beastie Boys, Kiss and Billy Squire.
So far, it is the 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 unit which operating under Joint Special Operations Command (JSOC).
