This is the most awesome Delta Force recruiting video we've ever seen

It's an oldie but a goodie — and it's likely the only publicly-available video showing real-deal Delta Force operators.

Leaked during the height of the Iraq war in 2008, this video crept its way onto YouTube and caused quite a splash when it hit the net. Rumors around the video claimed it was put together by the 1st Special Forces Operational Detachment-Delta to help recruit new members to "The Unit."

As that Tier 1 Joint Special Operations group was tasked with fighting the top leaders of the insurgency in Iraq, veterans of the unit from the '90s and 2000s were burning out — and suffering casualties. In fact, "No Easy Day" author and former SEAL Team 6 commando Matt Bissonnette wrote that some DEVGRU SEALS were tasked to run with Delta in Iraq because the squadrons were under manned.

So it stands to reason that Delta needed new blood. And with an assessment that matriculates only a handful who try, combined with a brutal operational tempo at the time that saw squadrons executing sometimes three raids per night for a 90 day deployment, The Unit had to get soldiers in the door.

The video is about as badass as it gets. With an AC/DC "Shoot to Thrill" soundtrack and all the sexiest gear you can imagine, the operators show lots of cool tactics and the training they go through.

Tactical driving? Check. Vehicle takedowns from a Little Bird? Check. Lots of breaching and A-10 CAS? Check.

But most awesome of all (and for those who look carefully) viewers can see one of the final exams for Delta operators during their assaulter courses.

At about 12:13 you see an assaulter team pouring through the door firing. Then it cuts to a person sitting in a chair with his arms up around his ears ducking.

According to Eric Haney who wrote the book "Inside Delta Force," this is sometimes used as a final exam for operators who alternate being in a chair in the middle of the shoot house room while his mates are live firing against targets near him. It's meant to build trust within the team and to deliver a sober reminder to Delta shooters not to hit the hostage they're there to rescue.
