Delta Force and the CIA’s paramilitary arm are both elite and secretive, but they sit in different chains of command, answer to different laws, and are used for different kinds of missions.wikipedia+2

What “Delta Force” is and who controls it

How Delta Force is used

Delta is a military tool for the hardest, often time‑sensitive missions, usually when the U.S. role can be acknowledged.

Typical mission types include:

Because it is a military unit, its operations are covered by the laws of armed conflict and the normal Pentagon chain of command and oversight (Secretary of Defense, Joint Chiefs, congressional armed services committees).greydynamics+1

CIA paramilitary forces: what they are and who controls them

So the chain looks roughly like: President → National Security Council → CIA Director → Special Activities Center (SAC/SOG).irp.fas+2

How CIA paramilitary units are used

SAC/SOG provides a politically deniable option where using overt U.S. military forces would be too escalatory or embarrassing.

Typical uses include:

One historical example: CIA paramilitary teams inserted into Tibet selected, trained, and then led Tibetan fighters against Chinese forces, and helped organize the Dalai Lama’s escape to India; this was never acknowledged publicly at the time.wikipedia+1

Key differences and “options” for policymakers

A useful way to see them is as different instruments in the president’s tool kit.

Strategists emphasize that covert operations, especially via CIA, give presidents a way to pursue objectives “incognito” and with more escalation control than open military action, though they pose their own risks and oversight problems.irp.fas+2
