"The unit" is the U.S. Army colloquial term for Delta Force. Its recruits are selected from the United States Army (primarily from the Ranger Regiment, Light Infantry, and Special Forces). The few who pass selection then undergo several more years of sophisticated and rigorous training for counter-terrorism, recon, and direct-action missions. In a TV interview, series creator Eric Haney—who is a former Delta Force operator—stated that the term "Delta Force" is never used in the spec ops community. They are only referred to as "the unit," and their DOD designation is "Combat Applications Group." The official cover name of the unit in the show is the similar sounding "303rd Logistical Studies Group." In the third season's premiere, an onscreen read-out specifically identifies the unit as "1st Special Actions Group," which is reminiscent of 1st Special Forces Operational Detachment-Delta.
