Extraction (military)

In military tactics, extraction is the process of removing personnel or units from an area; when conducted with stealth in an area controlled by the enemy it is referred to as exfiltration.
An example of a hostile extraction was Battle of [Boz Qandahari], in which U.S. Army Special Forces used donkeys to reach their extraction point while under enemy fire. Another example of an extraction was the joint United [States of America|U.S.] Central Intelligence Agency-Canadian government operation to smuggle six fugitive American diplomatic personnel out of revolutionary Iran in 1980 in an operation later known as the Canadian Caper.
