The unit is under the organization of the
U.S. Army Special Operations Command (USASOC), and 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. Details about specific missions or operations generally are not available publicly. The unit is headquartered at
Fort Bragg,
North Carolina. Delta Force's structure is similar to the British 22 SAS Regiment, which inspired Delta's formation. In 2001's
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, 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. 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 Squadron (Assault) • B Squadron (Assault) • C Squadron (Assault) • D Squadron (Assault) •
E Squadron (Aviation) • G Squadron (
Advanced Force Operations) • Signal Squadron • Combat Support Squadron • Combat Development Directorate • Selection and Training A, B, C, and DSquadrons are
sabre squadrons (assault). CSquadron was activated around 1990 and DSquadron in 2006. Combat Support Squadron was activated in 2005. ESquadron 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 saber squadron there are three troops: troops 1 and 2 (assault) and troop 3 (
reconnaissance). Each squadron is led by a
lieutenant colonel (
O-5), an executive officer, and a
command sergeant major (E-9). Troops are led by
captains (O-3) or
majors (O-4) known as the troop commanders who are assisted by
sergeants major (E-9), known as troop sergeants major. Each assault 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 have the same rank. Each team usually has five or six members.
Recruitment Since the 1990s, the Army has posted recruitment notices for the 1st SFOD-D. The Army has never released an official fact sheet for the unit. The recruitment notices in Fort Bragg'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...". The notice states that applicants must be in the grade of
E-4 to E-8, have at least two and a half years of service remaining in their enlistment, be 22 years or older, and have an
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. In 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".
Selection process Selection is held twice a year at
Camp Dawson, West Virginia, and lasts four weeks. Selections take place in late March to late April, and late September to late October.
Eric Haney's 2002 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 run, an inverted crawl and a swim fully dressed. The candidates were then put through a series of
land navigation courses, one of which required them to travel at night while carrying a 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 march with a rucksack over rough terrain, that had to be completed in an unknown amount of time. This was colloquially known as "The Long Walk". 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. 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. 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. Former
Navy SEAL, DEVGRU and Delta operator Kevin Holland stated that in his selection class, 120 candidates started, 16 passed and eight finished OTC. The
Central Intelligence Agency's secretive
Special Activities Center (SAC) and more specifically its
Special Operations Group (SOG), often works with – and recruits – former operators from Delta Force.
Training According to
Eric Haney, the unit's Operator Training Course is approximately six months long. While the course is constantly changing, the skills taught broadly include the following: •
Marksmanship: • The trainees shoot without aiming at stationary targets at close range until they gain almost complete accuracy, then progress to moving targets. • Once these shooting skills are perfected, trainees move to a
shoot house and clear rooms of "enemy" targets – first one only, then two at a time, then three, and finally four. When all trainees can demonstrate the sufficient skill required, "hostages" are added to the mix. • Demolitions and
breaching: • Trainees learn how to pick many different locks, including those on cars and safes. • Advanced demolition and bomb-making using common materials. • Combined skills (the
FBI,
FAA, and other agencies were used to advise on the training of this portion of OTC): • The new Delta operators use demolition and marksmanship at the shoot house and other training facilities to train for hostage and counter-terrorist operations with assault and sniper troops working together. They practice terrorist or hostage situations in buildings, aircraft, and other settings. • All trainees learn how to set sniper positions around a building containing hostages. They learn the proper ways to set up a
tactical operations center (TOC) and communicate in an organized manner. Although Delta has specialized sniper troops, all members go through this training. • The students then go back to the shoot house and the "hostages" are replaced with other students and Delta Force members. Live ammunition is known to have been used in these exercises, to test the students, and build trust between one another. •
Tradecraft (during the first OTCs and Delta creation,
CIA personnel were used to teach this portion of the training): • Students learn different espionage-related skills, such as
dead drops,
brief encounters, pickups, load and unload signals, danger and safe signals,
surveillance and
counter-surveillance. •
Executive protection (during the first OTCs and creation of Delta, the
U.S. State Department's
Diplomatic Security Service and the
United States Secret Service were consulted and advised Delta): • Students take an advanced driving course to learn to use a vehicle or many vehicles as defensive and offensive weapons. • They then learn techniques for
VIP and diplomatic protection developed by the Secret Service and DSS. • Culmination exercise: • A final test requires the students to apply and dynamically adapt all of the skills that they have learned. Delta Force trains with other foreign
special operations units to improve tactics and increase relationships with them, including the Australian
Special Air Service Regiment, the British
Special Air Service, and Canada's
Joint Task Force 2.
Unit name In a 2010 article, Marc Ambinder reported that
Army Compartmented Elements (ACE) was a new cover name for Delta Force. However, Ambinder subsequently wrote an e-book about JSOC in which he reported that the Army Compartmented Elements is a different unit from Delta. In January 2022 it was reported that the name of the unit may have recently been changed to the 3rd Operational Support Group. == Secrecy ==
