LGBTQ+ military service refers to the participation of individuals who identify as lesbian, gay, bisexual, transgender, queer, or other sexual and gender minorities in the armed forces. Historically, many countries had policies that excluded or discriminated against LGBTQ+ individuals, but these policies have evolved over time, allowing for greater inclusion and acceptance. In the United States, the repeal of the Don't Ask, Don't Tell policy in 2011 marked a significant change, enabling openly LGBTQ+ individuals to serve in the military. Additionally, the Department of Defense has implemented policies to support transgender service members, ensuring they can serve openly and receive necessary medical care.
