Bans discrimination in the U.S. Armed Forces on the basis of a person’s gender identity, including a diagnosis or possible diagnosis of gender dysphoria. It prohibits specified actions by the Secretary concerned that would exclude, separate, deny reenlistment/accession, or withhold medical care from someone because of their gender identity.

The law also defines “gender identity” and creates clear personnel and medical‑care protections for service members and military applicants who are transgender or have a gender‑identity diagnosis.
