For most of American military history, LGBTQ+ service members had two options: hide or be discharged. The formal policies changed over time, but the underlying logic — that openly gay, lesbian, or bisexual people were incompatible with military service — remained consistent from World War II through the early twenty-first century. The eventual integration of openly LGBTQ+ service members into the military was hard-won, contested, and incomplete in ways that persist today.

The World War II Era and the Origins of Formal Exclusion

Before World War II, the military had no explicit regulations barring gay people from service. Sodomy was criminalized under the Articles of War, but there was no systematic screening process. That changed as the military scaled up for the war. The Selective Service began using psychiatric screening to identify and exclude "homosexuals," operationalizing the then-dominant medical view that homosexuality was a mental disorder. Those who were identified and discharged did not receive honorable discharges. The "blue discharge" — neither honorable nor dishonorable, but carrying lasting stigma — was disproportionately given to gay service members and, historians have noted, to Black service members as well. Recipients were barred from veterans' benefits under the GI Bill. The consequences were not merely symbolic.

The Cold War and the Lavender Scare

The postwar years brought new intensity to the exclusion. The Lavender Scare — a less-remembered parallel to McCarthyism's Red Scare — resulted in the systematic purging of suspected gay employees from federal agencies including the State Department. The logic, stated plainly by officials at the time, was that gay people were susceptible to blackmail and therefore security risks. The circularity of this reasoning — that the discrimination which made people susceptible to blackmail was itself justified by that susceptibility — was rarely acknowledged. Executive Order 10450, signed by President Eisenhower in 1953, made "sexual perversion" grounds for dismissal from federal employment. This policy shaped the culture of the military for decades.

Don't Ask, Don't Tell and Its End

The Clinton administration's 1993 compromise policy, known as "Don't Ask, Don't Tell," was understood differently by different constituencies. For some, it was a meaningful step: service members would not be asked about their sexual orientation and would not be discharged merely for being gay, as long as they did not disclose it or engage in same-sex conduct. For others, it codified a form of institutionalized lying and left service members vulnerable to discharge if they were outed by others. During its eighteen years in force, DADT resulted in approximately 13,000 discharges. Research from the Palm Center at the University of California Santa Barbara documented that many of these discharges occurred during periods of military need, including after the September 11 attacks, and that the policy had no measurable benefit for unit cohesion — the primary argument offered for its existence. DADT was repealed in 2011. The integration of openly gay, lesbian, and bisexual service members proceeded more smoothly than its opponents had predicted.

The Ongoing Struggle for Transgender Service Members

The story of transgender military service is more recent and more turbulent. The Obama administration lifted the ban on transgender service members in 2016. The Trump administration reinstated a version of the ban in 2019. The Biden administration reversed it again in 2021. The policy has been a political football in ways that DADT repeal, once achieved, was not. This tangent matters: the experience of transgender service members illustrates how legal inclusion and institutional acceptance are not the same thing. Even during periods when transgender service was nominally permitted, individual service members faced medical access barriers, command-level hostility, and administrative obstacles.

What Integration Has and Has Not Resolved

The formal integration of LGBTQ+ service members has not eliminated anti-LGBTQ+ bias from military culture. It has, however, established a legal baseline. Service members now have recourse. That is a meaningful change from an era in which discharge for homosexuality was not only permitted but required. The distance between those two points, measured in individual lives disrupted and careers ended, is very long.
