Young YPJ recruits take a break by dancing and singing traditional YPJ songs at dawn, near Derek City, Syria. The YPJ schedule is demanding and requires discipline - new soldiers in training get about 6 hours of sleep a night and wake up at 4 AM; their day consists of a full schedule of drills and classroom lessons. Before joining the YPJ many of the girls had never participated in physical activity or sports before. (Photo by Erin Trieb/NBC News)
