Four Americans died in the 2012 Benghazi attack: Ambassador Chris Stevens, Information Officer Sean Smith, and two CIA operatives,Glen Doherty and Tyrone Woods, both former Navy SEALs. Stevens is the first U.S. ambassador killed in an attack since Adolph Dubs was killed in 1979. Senior intelligence officials later acknowledged that Woods and Doherty were contracted by the Central Intelligence Agency, not the State Department as previously identified, and were part of a Global Response Staff (GRS), a team that provides security to CIA case officers and countersurveillance and surveillance protection.
Initial reports indicated that ten Libyan guards died; this was later retracted and it was reported that seven Libyans were injured. An early report indicated that three Americans were injured in the attack and treated at an American Military Hospital in Germany.
Since then, reports differ regarding the number of Americans wounded in the attacks. The ARB report released December 20, 2012 stated that two Americans were wounded. In March 2013 it was reported that the State Department said there were four injured Americans. In August 2013, CNN reported that seven Americans were wounded, some seriously.
Glen Anthony "Bub" Doherty (July 10, 1970 – September 12, 2012) of Encinitas, was a native of Winchester, Massachusetts, and a 1988 graduate of Winchester High School. Doherty was the second of three children born to Bernard and Barbara Doherty. He trained as a pilot at Embry–Riddle Aeronautical University before moving to Snowbird, Utah for several winters and then joining the United States Navy. Doherty served as a Navy SEAL sniper and combat medic, responded to the bombing of the USS Cole and had tours of duty in Iraq and Afghanistan. He left the Navy in 2005 as a petty officer first class. After leaving the Navy, he worked for a private security company in Afghanistan, Iraq, Israel, Kenya and Libya. In the month prior to the attack, Doherty as a contractor with the State Department, told ABC News in an interview that he personally went into the field in Libya to track down MANPADS, shoulder-fired surface-to-air missiles, and destroy them.
