The document discusses integrating women into infantry roles in the US Marine Corps. It notes that a RAND study found women would have higher attrition rates and serve less time. Integrating women would require increased spending on recruiting and training to maintain infantry numbers. It also discusses challenges with facilities, equipment fit, and potential impacts on unit cohesion seen in other contexts like fire and police departments. While the Secretary of Defense ordered all infantry roles open to women in 2015, the Marines expressed concerns about the results of their task force experiments that found all-male groups outperformed integrated groups in 93 of 134 tasks.
