In fiscal 2018, women represented 16.5 percent of the active-duty force, compared with 15.1 percent in fiscal 2004, making up a small share of the more than 1 million active-duty troops. In the most recent year examined, the Air Force and Navy had the highest number of female personnel, both around 20 percent, while the Marine Corps had the lowest, at less than 9 percent, the GAO said.
