For the first time in it’s nearly 250-year history, a female is going to become a U.S. Marine Corps infantry officer.

FOX’s Lucas Tomlinson has the details from the Pentagon:

In a historic first, a female Marine will become the first infantry officer in Marine Corps history after passing the grueling 13-week infantry officer school, which has a 25-percent wash out rate.

The woman, whose name has not been revealed, is the first of three dozen women who attempted the course.

Two years after then-Defense Secretary Ash Carter lifted the military’s ban on women serving in infantry and other combat jobs.

President Trump’s Chief of Staff and former Marine General John Kelly told reporters in January 2016 he feared the standards for women in the infantry would be lowered by agenda driven people in Washington.
