More women have served in Iraq and Afghanistan than in any other conflict in our nation's history, and today they compose about 15 percent of the armed services. Soldier Girls follows the experiences of three women in the Indiana National Guard -- one a young college student, one a single mother, and one a grandmother -- who chose to enlist for different reasons, never expecting they would go to war. Though quite far apart in age and in their political views, the three women become close friends, and through their daily interaction we see how military service changes their relationships with their families, their lovers, and their children.
