Meet the Beast: Mark “Oz” Geist

Mark “Oz” Geist is a member of the Annex Security Team that fought in the Battle of Benghazi, Libya, on September 11–12, 2012. A Colorado native, he served 12 years in the United States Marine Corps, including roles in infantry, surveillance and target acquisition, and intelligence, where he specialized in interrogation and translation after studying Persian Farsi.

After his military service, Mark worked as a Deputy Sheriff in Colorado, investigating crimes against children and serving in narcotics and intelligence units. He later became Chief of Police in Fowler, Colorado, before moving into private investigations and security work.

In 2004, he began contract security work in Iraq, providing protection for U.S. personnel and training Iraqi SWAT teams. He also served as a mentor and advisor to the security detail of Iraq’s former Prime Minister.

Mark’s career culminated in Benghazi, where he helped save the lives of more than 25 Americans during the attacks. He continues to recover from injuries sustained in the battle and is a co-author of the bestselling book 13 Hours: The Inside Account of What Really Happened in Benghazi.
