Delta Force, along with the Intelligence Support Activity, and its Navy and Air Force counterparts, DEVGRU (SEAL Team 6) and the 24th Special Tactics Squadron, are the U.S. military's tier one special mission units that are tasked with performing the most complex, covert, and dangerous missions directed by the President of the United States and the Secretary of Defense.[9][10]
Most Delta Force operators and combat support members are selected from the Army Special Operations Command's 75th Ranger Regiment and U.S. Army Special Forces, though selection is open to other special operations and conventional units across the Army and other military branches.[11][12]
Key military and government figures had already been briefed on this type of unit in the early 1960s. Charlie Beckwith, a Special Forces (Green Berets) officer and Vietnam War veteran, served as an exchange officer with the British Army's 22 Special Air Service Regiment during the Malayan Emergency. On his return, Beckwith presented a detailed report highlighting the U.S. Army's vulnerability in not having a SAS-type unit. U.S. Army Special Forces in that period focused on unconventional warfare providing training and medical care to indigenous resistance fighters, but Beckwith recognized the need for "not only a force of teachers, but a force of doers".[13] He envisioned highly adaptable and completely autonomous small teams with a broad array of special skills for direct action and counter-terrorism missions. He briefed military and government figures, who were resistant to creating a new unit outside of Special Forces or changing existing methods.[14]
Finally, in the mid-1970s, as the threat of terrorism grew, Pentagon and Army senior leaders appointed Beckwith to form the unit.[15] Beckwith estimated that it would take 24 months to get his new unit mission ready. Beckwith's estimate came from a conversation he had had earlier with Brigadier John Watts while in England in 1976. Watts had made it clear to Beckwith that it would take eighteen months to build a squadron, but advised him to tell Army leaders that it would take two years, and not to "let anyone talk (him) out of this." To justify why it would take two years to build Delta, Beckwith and his staff drafted what they dubbed the "Robert Redford Paper," which outlined its necessities and historical precedents for a four-phase selection/assessment process.[16]
Delta Force was established on 19 November 1977, by Beckwith and Colonel Thomas Henry.[17] In the meantime, Colonel Bob "Black Gloves" Mountel of the 5th Special Forces Group created a unit to bridge the short-term gap that existed until Delta was ready, dubbed Blue Light.[18] The initial members of the unit were screened from volunteers and put through a specialized selection process in early 1978, involving a series of land navigation problems in mountainous terrain while carrying increasing weight. The purpose was to test candidates' endurance, stamina, willingness to endure, and mental resolve. The first training course lasted from April to September 1978. Delta Force was certified as fully mission capable in fall 1979, right before the Iran hostage crisis.[19]
On 4 November 1979, 52 American diplomats and citizens were taken captive and held in the U.S. embassy in Tehran, Iran. Delta Force was tasked to plan and execute Operation Eagle Claw, the effort to recover the hostages from the embassy by force on the nights of 24 and 25 April in 1980. The operation was aborted due to helicopter failures. The review commission that examined the failure found 23 problems with the operation, among them unexpected weather encountered by the aircraft, command-and-control problems between the multi-service component commanders, a collision between a helicopter and a ground-refueling tanker aircraft, and mechanical problems that reduced the number of available helicopters from eight to five (one fewer than the minimum desired) before the mission contingent could leave the trans-loading/refueling site.[20][21]
After the failed operation, the U.S. government realized more changes were needed. The 160th Special Operations Aviation Regiment (Airborne), also known as the "Night Stalkers", was created for special operations requiring air support. The Navy's SEAL Team Six, an earlier incarnation of the current Naval Special Warfare Development Group, was created for maritime counter-terrorism operations. The Joint Special Operations Command was created for command and control of the military's various counter-terrorism units.
The unit is under the organization of the U.S. Army Special Operations Command (USASOC), but is controlled by the Joint Special Operations Command (JSOC). Command of 1st SFOD-D is a colonel's billet. Virtually all information about the unit is highly classified and details about specific missions or operations generally are not available publicly. The unit is headquartered at Fort Liberty, North Carolina.
Delta Force's structure is similar to the British 22 SAS Regiment, which inspired Delta's formation. In Not a Good Day to Die: The Untold Story of Operation Anaconda, Army Times staff writer Sean Naylor describes Delta as having, at the time (in 2001), nearly 1,000 soldiers, of whom about 250 to 300 are trained to conduct direct action and hostage rescue operations. The rest are combat support and service support personnel who are among the very best in their fields.[22]
Naylor further details Delta Force's structure in his book Relentless Strike: The Secret History of Joint Special Operations Command. He describes a few formations in Delta, primarily the following operational elements:
A, B, C, and D Squadrons are sabre squadrons (assault). C Squadron was activated around 1989/1990 and D Squadron around 2005/2006. Combat Support Squadron was activated in 2005. E Squadron was activated in 1989 and is stationed separately in Fort Eustis, Virginia, where it is known as the Aviation Technology Office. An earlier forerunner of the unit was known as SeaSpray.
Within each squadron there are three troops: troops 1 and 2 (assault) and troop 3 (reconnaissance).[22] Each squadron is led by a Lieutenant Colonel (O-5),[25] executive officer and a Command Sergeant Major (E-9). Troops are led by Captains (O-3) or Majors (O-4) and are assisted by Sergeants Major (E-9).[26] Each troop has four teams, each one led by a team leader, a Master Sergeant (E-8) or Sergeant First Class (E-7), and an assistant team leader who can also have the same rank. Each team usually has five or six members.[27][28]
Since the 1990s, the Army has posted recruitment notices for the 1st SFOD-D.[29][30] The Army, however, has never released an official fact sheet for the unit. The recruitment notices in Fort Liberty's newspaper, Paraglide, refer to Delta Force by name, and label it "...the U.S. Army's special operations unit organized for the conduct of missions requiring rapid response with surgical application of a wide variety of unique special operations skills...".[31] The notice states that applicants must be in the grade of E-4 through E-8, have at least two and a half years of service remaining in their enlistment, be 22 years or older, and have a Armed Services Vocational Aptitude Battery GT score of 110 or higher to attend a briefing to be considered for admission. Candidates must be airborne qualified or volunteer for airborne training. Officer candidates need to be O-3 or O-4. All candidates must be eligible for a security clearance level of "secret" and have not been convicted by court-martial or have disciplinary action noted in their official military personnel file under the provisions of Article 15 of the Uniform Code of Military Justice.
On 29 June 2006 during a session of the Committee on Armed Services, General Wayne Downing testified before the U.S. House of Representatives that "[t]he Delta Force is probably 70 percent Rangers who have come out of either a Ranger [to] Special Forces track or directly from [the] Ranger Regiment to Delta".[32]
Selection is held twice a year (late March to late April, and late September to late October) at Camp Dawson, West Virginia, and lasts 4 weeks. Eric Haney's book Inside Delta Force described the selection course and its inception in detail. Haney wrote that the course began with standard tests including push-ups, sit-ups, and a 2-mile (3.2 km) run, an inverted crawl and a 110-yard (330 ft; 100 m) swim fully dressed. The candidates were then put through a series of land navigation courses, one of which required them to travel 18 miles (29 km) at night while carrying a 40-pound (18 kg) rucksack. With every successive challenge, the distance to cover and the weight of the rucksack are increased, while less time is allotted. The final challenge was a 40-mile (64 km) march with a 45-pound (20 kg) rucksack over rough terrain that had to be completed in an unknown amount of time; this was also colloquially known as "The Long Walk".[33] Haney wrote that only the senior officer and NCO in charge of selection were allowed to see the set time limits, but all assessment and selection tasks and conditions were set by Delta training cadre.[15][1]
The mental portion of the testing began with numerous psychological exams. Each candidate was then called to face a board of Delta instructors, unit psychologists, and the Delta commander, who asked the candidate a barrage of questions and then dissected every response and mannerism to exhaust the candidate mentally. The commander then approaches the candidate and informs him if he has been selected. Those who passed the screening process underwent an intense six-month Operator Training Course (OTC), to learn counter-terrorism and counter-intelligence techniques, and training with firearms and other weapons. Participants were allowed very little contact with friends and family for the duration.[1]
In an interview, former Delta operator Paul Howe mentioned the high attrition rate of the Delta selection course. He said that out of his two classes of 120 applicants each, 12 to 14 completed the selection.[34][35] Former Navy SEAL, DEVGRU and Delta operator Kevin Holland stated that in his selection class 120 candidates started, 16 passed and 8 finished OTC.[36]
