This bill, titled the "Ensuring Military Readiness Not Discrimination Act," seeks to amend Title 10 of the United States Code to establish comprehensive nondiscrimination policies within the Armed Forces. It introduces a new section, 651a, which explicitly prohibits discrimination based on various protected characteristics in military service. Specifically, the legislation mandates that eligibility standards for military service must be based solely on an individual's ability to meet occupational requirements, explicitly excluding criteria related to race, color, national origin, religion, or sex . The definition of "sex" is broadened to include gender identity, sexual orientation, and sex characteristics (including intersex traits) . Additionally, the bill requires that all personnel policies developed by the Secretary concerned ensure equality of treatment and opportunity for all service members, without regard to these specified characteristics.
