History

Delta Force was created in 1977 after numerous well-publicized terrorist incidents led the U.S. government to develop a full-time counter-terrorism unit.
Key military and government figures had already been briefed on this type of unit in the early 1960s.

, but Beckwith recognized the need for "not only a force of teachers, but a force of doers". 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.

and Army senior leaders appointed Beckwith to form the unit. 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.
Delta Force was established on 19 November 1977, by Beckwith and Colonel Thomas Henry. In the meantime, Colonel Bob "Black Gloves" Mountel of the

created a unit "to breach the short-term gap" that existed until Delta was ready, dubbed
Blue Light. 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

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.
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 squadrons:
* A Squadron (Assault)
* B Squadron (Assault)
* C Squadron (Assault)
* D Squadron (Assault)

E Squadron (Aviation)
* G Squadron (

* Combat Support Squadron
* Signal Squadron
A, B, C, and DSquadrons are
saber squadrons (assault). CSquadron was activated in 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 squadron there are three troops: two assault troops for direct action, and a
reconnaissance and surveillance troop. Each squadron is commanded by a
Lieutenant Colonel (O-5) and troops are led by
Majors (O-4). 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 can have as many as twelve, or as few as one or two operators.
Recruitment
Since the 1990s, the Army has posted recruitment notices for the 1st SFOD-D. The Army, however, has never released an official fact sheet for the elite force. 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 male, in the grade of
E-4 through E-8, have at least two and a half years of service remaining in their enlistment, be 21 years or older, and score high enough on the
Armed Services Vocational Aptitude Battery 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.

'' described the selection course and its inception in detail. Haney wrote that the selection course began with standard tests including push-ups, sit-ups, and a run, an inverted crawl and a swim fully dressed. The candidates are then put through a series of land navigation courses to include an all-night land navigation course while carrying a rucksack. The rucksack's weight and the distance of the courses are increased and the time standards to complete the task are shortened with every march. The physical testing ended with a march with a rucksack over rough terrain that had to be completed in an unknown amount of time; this is also colloquially known as "The Long Walk". Haney wrote that only the senior officer and NCO in charge of selection are 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. The men then went in front of a board of Delta instructors, unit psychologists, and the Delta commander, who each ask the candidate a barrage of questions and then dissect every response and mannerism of the candidate to exhaust the candidate mentally. The unit commander then approaches the candidate and tells him if he has been selected. If an individual is selected for Delta, he undergoes an intense 6-month Operator Training Course (OTC), to learn

, the unit's Operator Training Course is approximately six months long. While the course is constantly changing, the skills taught broadly to 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, three, and finally four. When all can demonstrate sufficient skill, "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 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
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.
** 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.
*

Secrecy
The
Department of Defense tightly controls information about Delta Force and usually refuses to comment publicly on the highly secretive unit and its activities, unless the unit is part of a major operation or a unit member has been killed. Delta operators are granted an enormous amount of flexibility and autonomy during military operations overseas. Civilian hair styles and
facial hair are allowed to enable the members to blend in and avoid recognition as military personnel.
The term "operator"

The origin of the term "operator" in American special operations comes from the
U.S. Army Special Forces (aka the Green Berets). The Army Special Forces was established in 1952, ten years before the
Navy SEALs and 25 years before Delta. Every other modern U.S. special operations unit in the Army, Navy, Air Force, and Marines was established after 1977. In ''Veritas'', the Journal of Army Special Operations History, Charles H. Briscoe stated that the Army "Special Forces did not misappropriate the appellation. Unbeknownst to most members of the Army Special Operations Force (ARSOF) community, that moniker was adopted by the Special Forces in the mid-1950s." He goes on to state that all qualified enlisted and officers in Special Forces had to "voluntarily subscribe to the provisions of the 'Code of the Special Forces Operator' and pledge themselves to its tenets by witnessed signature." This pre-dates every other special operations unit that currently uses the term/title operator.
Inside the
United States Special Operations community, an "operator" is a Delta Force member who has completed selection and has graduated OTC (Operator Training Course). "Operator" was used by Delta Force to distinguish between combat personnel and combat support/service support assigned to the unit. Other
special operations forces use specific names for their jobs, such as Army Rangers and Air Force
Pararescuemen. The Navy uses the acronym SEAL for both their special warfare teams and their individual members, also known as "special operators". In 2006 the Navy created "Special Warfare Operator" (SO) as a rating specific to Naval Special Warfare enlisted personnel, grades
E-4 to
E-9. (See
Navy special warfare ratings). "Operator" has become a colloquial term for almost all special operations forces in the U.S. military and worldwide.
