The US Army’s highly secretive counterterrorist unit, 1st Special Forces Operational Detachment Delta, is without a doubt among the best counterterrorism units in the world.

While Delta is extremely well known, if only by its name, it wasn’t actually the first American counterterrorist force in existence. That honor goes to a different unit — now long lost to history — known as “Blue Light.”

Colonel Charlie Beckwith, a former Green Beret and the brains behind 1st SFOD-D, discussed the parallel history of Blue Light in his co-written book, “Delta Force.” Beckwith, after serving an exchange tour with the British Special Air Service, returned to the US with an idea for a dedicated counterterrorist unit, similar to the SAS.

With terrorism on the rise throughout the 1970s, it became imperative for the US military to create a force that would deal with terror threats with precision and extreme effectiveness.

The firebrand colonel would go on to outline his concept to the Pentagon, particularly Army generals and fellow colonels with enough sway to allocate funding for such a unit. Beckwith encountered resistance — especially from “old guard” officers who disagreed with allowing Delta to exist on its own with its own funding.

Rather, they felt that Delta needed to remain within an already established pecking order in the asymmetric warfare community — the US Army’s Special Forces.

Despite its official title, Delta Force had absolutely nothing to do with Army Special Forces Operational Detachments, also known as “A-Teams.” The title was just another vaguely-misleading cover for the unit’s real purpose.

Delta, instead, would have a direct line through the Department of Defense to the president’s office, circumventing Special Forces altogether. Further incensing the brass was the fact that Delta would be given free rein to recruit whoever interested them, including experienced Green Berets from the groups.

Inner-Army politicking quickly led to Special Forces brass deciding it would create a counterterrorist unit of its own, ostensibly as an interim solution while Delta was getting up to speed, but with the inward hopes of it being a more permanent fixture.

The new unit — Blue Light — was staffed with commandos brought in directly from 5th Special Forces Group’s 2nd Battalion into a subordinate unit. There, they would be trained in an array of skills necessary for counterterrorist mission and be readied for real-world operations. Colonel Bob “Black Gloves” Mountel would be responsible for helming the new unit in its infancy.

Blue Light would only be equivalent to a company-sized element of troops, but would still draw its funding from Special Forces, and would push its members through further airborne and dive training, weapons courses and more.

It was assumed that because Green Berets were already highly-trained for asymmetric warfare, they would be ready to fight far quicker than Delta.

In the meanwhile, Beckwith and his cadre got to work designing and training the founding members of Delta Force, still very aware of the potential for Blue Light to completely take over their mission and tank 1st SFOD-D before it could even get off the ground.

Blue Light was beefed up with the presence of veteran operatives with significant combat experience under their belts, including Joseph Cincotti, a Vietnam-era Green Beret who would later go on to head up the John F. Kennedy Special Warfare Center and School, and who was responsible for creating the curriculum all Special Forces candidates undergo today.

In their book, “Special Forces: A Guided Tour of US Army Special Forces,” authors Tom Clancy and John Gresham claim that Blue Light was somewhat handicapped from the start. While Delta was designed to operate in every conceivable environment, using a multitude of mission-relevant skills, Blue Light was, in reality, only prepared for a few contingencies.

Little by little, Delta Force took shape at Fort Bragg, NC, and by the end of the 1970s, Delta was ready for action. Bragg was also the home of Blue Light, and the rivalry between the two counterterrorist units was palpable. Former operator Eric Haney discusses the animosity between Blue Light and the 1st SFOD-D in his book, “Inside Delta Force.”

When Delta was declared fully operational, Blue Light faded into the shadows, eventually being disbanded in 1978. Its former members were either transferred to other units within the Army’s various Special Forces groups, or decided to retire altogether.

Beckwith, not willing to let an opportunity pass, extended invites to Blue Light commandos to try out for Delta Force, and at least four of the former counterterrorist unit’s operatives successfully passed selection and the arduous Operator Training Course to become Delta Force operators.

Former Blue Light officers would later play a part in planning Operation Eagle Claw, the failed mission to rescue American hostages in Iran in 1980.
