Fit to Serve Act

Prohibits the Armed Forces from taking personnel or medical actions based on a person’s gender identity. It bars actions such as setting qualifications, separating or discharging someone, denying medically necessary care, forcing a person to serve according to the sex assigned at birth, or refusing enlistment or reenlistment because of gender identity, and it defines "gender identity." This creates a statutory nondiscrimination rule that requires military personnel and policy to treat gender identity as a protected characteristic for the listed personnel actions.
