Pfc. Angelika Jansen and Pfc. Jessica Jones stand near a Paladin M109 self-propelled howitzer at Vincent Hall on Fort Lee, Va., July 3, 2013. The two Soldiers, who were awarded the Artillery Mechanic military occupational specialty, or MOS, were the first two females to earn the designation. The MOS was one of six that were chosen last year to open its ranks to female Soldiers. The Department of Defense has a goal to make all MOSs open to female applicants by 2016.
