The United States Army Special Forces, is a special operations force tasked with five primary missions: unconventional warfare, foreign internal defense, special reconnaissance, direct action, and counter-terrorism. Other duties include combat search and rescue (CSAR), counter-narcotics, counter-proliferation, hostage rescue, humanitarian assistance, humanitarian demining, information operations, peacekeeping, psychological operations, security assistance, and manhunts; other components of the United States Special Operations Command (USSOCOM) or other U.S. government activities may also specialize in these secondary areas.
Special Forces are divided into five active duty and two Army National Guard, Special Forces groups. Each Special Forces Group (SFG) has a specific regional focus. The Special Forces soldiers assigned to these groups receive intensive language and cultural training for countries within their regional area of responsibility (AOR). Due to the increased need for Special Forces soldiers in the War on Terror, all Groups—including those of the National Guard (19th and 20th SFGs)—have been deployed outside of their areas of operation (AOs), particularly to Iraq and Afghanistan.
