Delta Force is the Army’s special mission unit for counterterrorism and hostage rescues.

Created in the late 1970s in the image of the British Special Air Service (SAS), Delta Force has been at the very tip of the U.S. military spear for decades.

The Unit, as Delta Force operators refer to it, has been involved in all major and minor U.S. military operations and campaigns since its formation, including in Iran, Panama, Grenada, Somalia, Bosnia, Afghanistan, Iraq, and Syria.

Delta Force is part of the secretive Joint Special Operations Command (JSOC) alongside its Navy counterpart, SEAL Team Six, and some other special mission units that specialize in intelligence gathering and covert and clandestine transportation.

With an attrition rate historically hovering at 90 percent, Delta Force has one of the hardest and most selective selection and assessment processes in the U.S. military.

Considered the cream of the crop of U.S. special operations, Delta Force’s selection process reflects its vaunted status.

Anyone can volunteer for the course, formally known as Assessment and Selection, regardless of their service branch or status (active duty, national guard, or reserves).

“In my time, it was usually about 60 percent Green Berets, 39 percent Rangers, and 1 percent random guys, such as cooks, chaplain assistants, and mechanics. We even had a flute player from the Army band try out in my Selection, but he didn’t make it,” George Hand IV, a retired Delta Force operator, told Insider.
