Much of what DEVGRU, or the Naval Special Warfare Development Group, is and does remains classified and unknown. What is know is that they were formed
in the mid 1990's after SEAL Team Six, the Navy's Counter-terrorism was disbanded. DEVGRU was created after Richard Marcinko, the original commander
of ST6 published a series of books that outlined the history and purpose of the original Team. According to the US Navy, DEVGRU was formed to create,
test, and evaluate new tactics, weapons, and equipment.
However, with the disbanding of ST 6 the Navy was left without a maritime CT unit, although SEAL Team 8 was tasked with maritime deployments and
takedowns. Recent rumors have appear to confirm that DEVGRU is actually a CT unit created (although current officers will deny its existance) to
replace the lime-light stricken ST6. This is born out, in no small significance, buy the structure surroundind DEVGRU. While under the command of
NAVSPECWARGRU (Navy Special Warfare Group, DEVGRU is also a component of JSOC, with other such units as the US Army's 1st SFOD-D and 160th Special
Operations Aviation Regiment, both units that list counter-terrorism in their promary activities.
The U.S. Army’s 1st Special Forces Operational Detachment-Delta (SFOD-D) is one of two of the U.S. government’s principle unit tasked with
counterterrorist operations outside the United States (the other being Naval Special Warfare Development Group). Delta Force was created by U.S. Army
colonel Charles Beckwith in 1977 in direct response to numerous, well-publicized terrorist incidents that occurred in the 1970s. From its beginnings,
Delta was heavily influenced by the British SAS, a philosophical result of Col. Beckwith’s year-long (1962-1963) exchange tour with that unit.
Accordingly, it is today organized into three operating squadrons, all of which (A, B, and C) are subdivided into small groups known as troops. It is
rumored that each troop, as the case with the SAS, specializes in HALO, SCUBA, or other skill groups. These troops can each be further divided into
smaller units as needed to fit mission requirements. Delta also maintains support units which handle selection and training, logistics, finance, and
the unit’s medical requirements. Within this grouping is a little known, but vital technical unit which is responsible for covert eavesdropping
equipment for use in hostage rescues and similar situations.
The unit is headquartered in a remote section of the U.S. Army’s sprawling Fort Bragg, North Carolina. Reports of the compound indicate that no
expense has been spared, including numerous shooting facilities (both for close quarters battle and longer range sniping), an Olympic-sized swimming
pool, dive tank, and a three-story climbing wall. Yet, as lavish as these accouterments may seem, they all serve vital roles in training
counterterrorists. As units such as Delta do not get to choose when and where they will be needed. As such, they must train for any eventuality. These
skills are enhanced by the unit's participation in an ongoing exchange and training programs with foreign counterterrorist units, such as (as might
be expected) Britain's 22 SAS, France's GIGN, Germany's GSG-9, Israel's Sayeret Matkal/Unit 269, and Australia's own Special Air Service
Regiment. Such close cooperation with other groups provides innumerable benefits, including exchanges of new tactics and equipment as well as
enhancing relations that might prove useful in later real-world operations.
Delta troopers are also equipped with the most advanced weaponry and equipment available in the U.S. special operations arsenal. A significant portion
of their gear is highly customized and cannot be found anywhere but in Delta’s lockers. An early example of this was a specially-constructed HAHO
parachute rig which were been adapted to permit jumpers to keep their hands at their sides during the descent rather than above their heads. This
alteration prevents the loss of functioning which can occur as a result of prolonged flight time in such an unnatural position.
