The lieutenant was one of 88 Marines to complete the grueling 13-week course which "trains and educates newly selected infantry and ground intelligence officers in leadership, infantry skills, and character required to serve as infantry platoon commanders in the operating forces."
More than 30 female officers have attempted the infantry officer course since 2015 when the Pentagon ended its ban on women serving on the front lines, Business Insider reports.
"This is such a huge deal," Kate Germano, who is a retired Marine Corps lieutenant colonel, tweeted. "My hope is that she is never an officer who says she never considered her gender as being an issue in her career."

In a column for the San Diego Tribune, Germano called on the U.S. military to "encourage more women to pursue ground combat jobs and change the strong perception that the service is resistant to women serving in these new roles."
The female lieutenant will now be heading to the 1st Marine Division at Camp Pendleton, California, for her first assignment.
