The Marine Corps has gone to great lengths hiding identities of the first female students to attend their officer and enlisted infantry courses.

But then one of them turned up on Facebook with a bloody face in a posed photo.

We're not going to link to the explicit military Facebook page that posted the photo, but solid sources have verified to Business Insider that the pictured Marine is indeed one of the females attending the course.

Moreover, it looks like she has an Instagram page, which features several pictures from Infantry School and of her injury, with a note that she suffered the injury when a Kevlar helmet fell from the top of her locker.

Her social media use may show bad judgment — Marines are warned explicitly against posting photos — but, needless to say, she seems untroubled by the challenges of the course.

In January, then-Defense Secretary Leon Panetta cleared women to enter combat arms job fields in the military. Since then, the Marine Corps has started a pilot program to see if women are even capable of completing the rigorous infantry training without lowering the standards — those being just the basic physical standards required of men to be infantry.

Since then, six women have failed the officer's infantry course pilot program. The Corps intends to run 100 women through the program in a year's time.

Fifteen women recently became the first trainees in the Corps' enlisted program.

Notably, if any of these women pass the course, they will not earn the infantry rating. The pilot course is simply to test if women are capable of passing existing standards.

Any women who complete the course will then go on to another job school.

So essentially, these women are doing it strictly for posterity's sake.

Finally, this image of hers loaded to a personal account sums up her experience training with the grunts:
