A female Marine lieutenant has become the first woman in history to graduate from the United States Marine Corps (USMC) Scout Sniper Unit Leaders Course. Previously, the Marine officer, who is a candidate for a Ground Intelligence Officer (0203) Military Occupational Specialty (MOS), was the second female to successfully complete the Infantry Officer Course.

She is now almost qualified to lead a Scout Sniper platoon or apply for reconnaissance training. According to the Marine Corps Training and Education Command, the female officer had, in fact, finished Scout Sniper school back in July, but due to operational security reasons, it wasn’t publicized until now.

The three-week school trains junior officers (from lieutenant to captain) and non-commissioned officers on how to best employ Marine snipers to increase their lethality and effectiveness on the battlefield and thus, better accomplish any mission they face. It was held at Quantico, Virginia.

The school, however, shouldn’t be confused with the basic Scout Sniper course, which junior enlisted Marines attend to in order to become qualified snipers. That school is two-and-half months long and one of the more intensive training programs in the entire USMC.
