The 1st Special Forces Operational Detachment–Delta (1st SFOD-D), also known as Delta Force, Combat Applications Group (CAG), or within Joint Special Operations Command (JSOC) as Task Force Green, is a special operations force of the United States Army under the operational control of JSOC. The unit's missions primarily involve counterterrorism, hostage rescue, direct action, and special reconnaissance, often against high-value targets.

Delta Force, along with the Intelligence Support Activity, and its Navy and Air Force counterparts, DEVGRU (SEAL Team 6) and the 24th Special Tactics Squadron, are the U.S. military's tier one special mission units that are tasked with performing the most complex, covert, and dangerous missions directed by the president of the United States and the secretary of defense.

A United States Air Force Special Tactics Officer (AFSC 19ZXA) is a United States Air Force Special Operations Command (AFSOC) special warfare officer who manages the training and equipping of U.S. Air Force ground special operations. Special Tactics Officers deploy as team leaders or mission commanders in combat, seizing and controlling airstrips, combat search and rescue, guiding airstrikes and fire support using air assets for special operations and tactical weather observations and forecasting. Special Tactics Officers are not pararescuemen, combat controllers, or special reconnaissance, but they lead the Special Tactics Squadrons and Groups and thoroughly understand how to conduct, manage, and provide these special operations missions to both conventional and joint special operations missions needed within Joint Special Operations Command (JSOC) and United States Special Operations Command (SOCOM).

The 75th Ranger Regiment, also known as the Army Rangers, is the United States Army Special Operations Command's premier light infantry and direct-action raid force. The 75th Ranger Regiment is also part of Joint Special Operations Command via the Regimental Reconnaissance Company (RRC). The regiment is headquartered at Fort Benning, Georgia, and comprises a regimental headquarters company, a military intelligence battalion, a special troops battalion, and three Ranger battalions.

The 75th Ranger Regiment primarily handles direct-action raids in hostile or sensitive environments, often killing or capturing high-value targets. Other missions include airfield seizure, special reconnaissance, personnel recovery, clandestine insertion, and site exploitation. The regiment can deploy one Ranger battalion within 18 hours of alert notification.

The Intelligence Support Activity (ISA), also known at various times as Mission Support Activity (MSA), Office of Military Support (OMS), Field Operations Group (FOG), Studies and Analysis Activity (SAA), Tactical Concept Activity, Tactical Support Team, Tactical Coordination Detachment, and also nicknamed "The Activity" and the "Army of Northern Virginia", is a United States Army Special Operations unit which serves as the field military intelligence gathering component of Joint Special Operations Command (JSOC). Within JSOC, the unit is often referred to as Task Force Orange.

Originally subordinated to the United States Army Intelligence and Security Command (INSCOM), it is one of the least known intelligence components of the United States military, tasked with clandestine human intelligence operations and collecting actionable intelligence during or prior to JSOC missions.

The 24th Special Tactics Squadron is a special tactics unit of the United States Air Force Special Operations Command (AFSOC). Garrisoned at Pope Field, North Carolina, it is the U.S. Air Force component of Joint Special Operations Command (JSOC). The unit's webpage describes it as "the Air Force's special operations ground force".
