The Marine Corps continues to be the only service where men and women train separately in boot camp or basic training. This segregation negatively affects interaction with male marines later on, and, lower expectations of female recruits are actively maintained and encouraged. But Lieutenant Colonel Kate Germano arrived at the Fourth Recruit Training Battalion at Parris Island--which exclusively trains female recruits--convinced that if she expected more of the women just coming into Corps, she could raise historically low standards for female performance and make women better Marines. And, after one year, shooting qualifications of the women under her command equaled those of men, injuries had decreased, and unit morale had noticeably improved. Then the Marines fired her. This is the story of Germano's struggle to achieve equality of performance and opportunity for female Marines against an entrenched male-dominated status quo. It is also a universal tale of the effects of systemic gender bias.
