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, this is referred to as exfiltration.^[1]

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.^[2] Another example of an extraction was the joint 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.^[3]
