1st Special Forces Operational Detachment-Delta (1st SFOD-D)

Operations

According to the book Inside Delta Force by CSM Eric L. Haney (ret.), the smallest unit is a team, consisting of four to five members. Each team specializes in HALO/HAHO, SCUBA, or other skill groups. The next tier is the troop level, consisting of four to five teams. Finally, squadron level (there are four squadrons) consists of two troops (Assault and Sniper). Squadrons are broken down into troops and teams as needed to fit mission requirements.

Each individual member of Delta is known as an operator such as in the Australian SAS. This was to avoid confusion with the CIA's  term operative.

In "Not A Good Day To Die: The Untold Story Of Operation Anaconda", Army Times staff writer Sean Naylor describes Delta as having nearly 1,000 soldiers. Naylor wrote that only 250 of those are operators trained to conduct direct-action and reconnaissance missions. Those soldiers are divided into three squadrons—A, B, and C—with each squadron subdivided into three troops. Two are assault troops while a third troop specializes in reconnaissance and surveillance and is known as the "recce" troop. The remaining soldiers in Delta are highly trained specialists in mechanics, communications, intelligence and other support activities, and a headquarters staff. Naylor also wrote that Delta maintains an aviation squadron based somewhere else on the East Coast.

SFOD in Modern Conflicts

One of several operations in which Delta Force operators are thought to have played important roles was the invasion of Iraq in 2003. They allegedly entered Baghdad in advance, undercover with long hair and moustaches, along with SEALs from DEVGRU, guiding air strikes, building networks of informants while eavesdropping on and sabotaging Iraqi communication lines.

The force was also involved in the offensive against the Taliban in Afghanistan in 2002.  Many observers strongly suspect that members of Delta Force made up one of two units involved in a raid on a residence belonging to Mullah Omar. According to the Pentagon, the level of resistance to that operation was minimal.

The Mullah was not present but some papers and computer disks were said to have been seized in the raid. Critics later alleged that the second unit was unnecessary, claiming that it was very large and uncoordinated. As a result, they say, the defenders were alerted early and the number of friendly casualties was in fact higher than reported. According to the book Shadow Wars by David Pugliese, Delta operators wanted a quiet insertion method which was denied as command opted for a combined Ranger assault. Taliban fighters apparently ambushed the team when they were extracting and several Delta operators were severely wounded.

Delta Force operators are granted an enormous amount of flexibility and autonomy, as with their Navy counterpart, DEVGRU. They reportedly do not maintain any general uniformed presence and civilian clothing is the norm on or off duty while at Ft. Bragg. This is done to conceal the identities of these "secret soldiers". Uniforms are rarely worn, if at all, with any markings, names, or branch names on them. Hair styles and facial hair are allowed to grow to civilian standards in order for the force to be able to blend in and not be immediately recognized as military personnel.

This special status that sets the force apart from the "regular army" is depicted quite accurately in the book Black Hawk Down by Mark Bowden, and the film of the same name. The Army Rangers in the media, elite by their own right, have the standard "high and tight"  haircuts (**Rangers no longer sport the high & tight, as their mission has drastically changed), yet the Delta operators are seen to be sporting much longer styles with side burns, un-shaven faces, and non-military issue helmets (actually hockey helmets, more to protect from bumps and scrapes while entering buildings than against gunfire, as noted in the book) and boots.

According to Black Hawk Down: A Story of Modern War, Delta Force members are typically referred to by other personnel as "D-Boys", "Operators", "Rocks", or simply "Delta". The book also mentions that they hold little regard for rank within their force and refer to one another only by nicknames. Throughout the book Delta soldiers are recorded as expressing contempt for other, more regular US Army units, dismissing their training and combat performance.

Delta's unconventional nature also allows its operators to carry highly customized weapons. Although their standard weapon of choice may be the M4 carbine, they also use the SOPDMOD Special Operations Peculiar Modification) kit on the M4, and it is not unusual to find them carrying foreign weapon systems that are often used by the enemy in the Area of Operation (AO). This is to either help them "blend in" with the locals or to use the ammunition from slain enemy fighters.

Additionally, in his book Killing Pablo, Mark Bowden suggests that a Delta Force sniper may have assassinated Colombian drug lord Pablo Escobar. There is no hard evidence of this though and credit is generally attributed to Colombian security forces.
