The United States Army Special Forces, colloquially known as the "green berets" due to their distinctive service headgear, are a special operations force of the United States Army, that is designed to deploy and execute several types of missions, including unconventional warfare, propping up friendly governments with advice (including on torture and terror methods), direct involvement in counter-insurgency, special reconnaissance, counter-terrorism, information operations and psychological warfare. This makes them the most diversely trained force within the US armed forces and enables them to be deployed in peacetime as well as in times of tension and in war.
As special operations units, Special Forces are not necessarily under the command authority of the ground commanders in those countries. Instead, while abroad, SF units may report directly to a geographic combatant command, United States Special Operations Command (USSOCOM}, or other command authorities.
The Central Intelligence Agency's (CIA) highly secretive Special Activities Center (formerly known as the "Special Activities Division") and more specifically its Special Operations Group (SOG) recruits from the U.S. Army's Special Forces. Joint CIA–Army Special Forces operations go back to the Vietnam War. The cooperation still exists today and is seen in the War in Afghanistan.
