Women have played critical roles in the U.S. military for decades and the Obama administration's recent decision to lift a ban on women in combat has furthered gender equality in the armed forces.
Hospital Corpsman Shannon Crowley, 22, a U.S. Navy Sailor working with the FET (Female Engagement Team) 1st Battalion 8th Marines, Regimental Combat team II patrols with male Marines, Nov. 18, 2010 in Musa Qala, Afghanistan. The U.S. had deployed 48 women along the volatile front lines of the war in Afghanistan, in order to gain access where men can't. The women, many of whom volunteer for the 6.5 month deployment, take a 10-week course at Camp Pendleton in California where they are trained for any possible situation, including learning Afghan customs and basic Pashtun language.

Hegar, a California Air National Guard pilot who served three tours in Afghanistan, was one of four female military service members who filed a lawsuit last year to challenge the Pentagon ban on women in combat. Hegar argued that excluding women from a draft reinforces a stereotype that they are less capable than men and need to be protected.

U.S. Army Staff Sergeant Walter Challapa (R) instructs an Iraqi female trainee at the firing range of a paramilitary training camp in Amiriyah, west of Baghdad, in May 2004. The female trainees are all employees at the camp, jobs that come with some risk since sections of Iraqi society view them as American collaborators. They helped take over the security of Iraq when U.S. troops finally departed, with some expected to join the Iraqi Civil Defence Corps (ICDC), serving at checkpoints and searching women suspects.
