PHOTOS: First women soldiers from US army's toughest school

For 120 days, they underwent gruelling training in swamps, across mountains and woods. They spent sleepless nights as they undertook challenging hikes and faced rigorous combat training. After all of that and more, two women have made history.

Captain Kristen Griest and First Lieutenant Shaye Haver are the first women ever to graduate from the United States army’s ranger school, designed to produce elite and tough soldiers. Along with 94 male counterparts, the duo on Friday received the coveted Black and Yellow Ranger Tab.

This is the first year women attended the training after US President Barack Obama ordered the military to accept women in combat roles by 2016. 

At the arduous programme, candidates train up to 20 hours each day. And here’s how Griest and Haver got going.

"We felt like we were contributing as much as the men," Griest told CNN. In this image, you can see her participating in an obstacle course as part the training at the US army school. Photograph: Scott Brooks/US army via Getty Images

When Griest and Haver (seen in this picture) completed the daunting US army ranger school this week they helped end questions about whether women can serve as combat leaders, as the Pentagon is poised to open new roles, including elite Navy SEALs, to women in coming months.
