"Don't ask, don't tell" (DADT) was the official United States policy on military service of non-heterosexual people. Instituted during the Clinton administration, the policy was issued under Department of Defense Directive 1304.26 on December 21, 1993, and was in effect from February 28, 1994, until September 20, 2011. The policy prohibited military personnel from discriminating against or harassing closeted homosexual or bisexual service members or applicants, while barring openly gay, lesbian, or bisexual persons from military service. This relaxation of legal restrictions on service by gays and lesbians in the armed forces was mandated by Public Law 103–160, which was signed November 30, 1993. The policy prohibited people who "demonstrate a propensity or intent to engage in homosexual acts" from serving in the armed forces of the United States, because their presence "would create an unacceptable risk to the high standards of morale, good order and discipline, and unit cohesion that are the essence of military capability".
Lesbian, gay, bisexual, transgender, and queer (LGBTQ) personnel are able to serve in the armed forces of some countries around the world: the vast majority of industrialized, Western countries including some South American countries, such as Argentina, Brazil and Chile in addition to other countries, such as the United States, Canada, Japan, Australia, Mexico, France, Finland, Denmark and Israel. The rights concerning intersex people are more vague.

California National Guard, 124 F.3d 1126 was a federal court case heard by the Ninth Circuit Court of Appeals, that upheld the "don't ask, don't tell" policy that restricted service by gays and lesbians in the California National Guard of the United States.

Unfriendly Fire: How the Gay Ban Undermines the Military and Weakens America is an American 2009 political book by Nathaniel Frank that argues that the "Don't Ask, Don't Tell" policy banning openly gay servicemen and women from the United States armed forces weakened military and national security. According to Frank, 12,000 people — 800 of whom had previously been deemed "mission critical" by the U.S. government — were discharged from the military between 1993 and 2008, based on policies that Frank describes as "rooted in denial, and deception, and repression."
The United States military formerly excluded gay men, bisexuals, and lesbians from service. In 1993, the United States Congress passed, and President Bill Clinton signed, a law instituting the policy commonly referred to as "Don't ask, don't tell" (DADT), which allowed gay, lesbian, and bisexual people to serve as long as they did not reveal their sexual orientation. Although there were isolated instances in which service personnel were met with limited success through lawsuits, efforts to end the ban on openly gay, lesbian, and bisexual people serving either legislatively or through the courts initially proved unsuccessful.
Log Cabin Republicans v. United States, 658 F.3d 1162 was a federal lawsuit challenging the constitutionality of 10 U.S.C. § 654, commonly known as don't ask, don't tell (DADT), which, prior to its repeal, excluded homosexuals from openly serving in the United States military.

Witt v. Department of the Air Force, 527 F.3d 806 is a federal lawsuit that challenged the constitutionality of 10 U.S.C. § 654, the law, since repealed, that excluded openly homosexual people from serving in the United States military, commonly known as "Don't ask, don't tell" (DADT). The United States Court of Appeals for the Ninth Circuit ruled in 2008 that under Lawrence v. Texas DADT constitutes an "[attempt] to intrude upon the personal and private lives of homosexuals" and it is subject to "heightened scrutiny", meaning that the government "must advance an important governmental interest, the intrusion must significantly further that interest, and the intrusion must be necessary to further that interest."
The Don't Ask, Don't Tell Repeal Act of 2010 is a landmark United States federal statute enacted in December 2010 that established a process for ending the "don't ask, don't tell" (DADT) policy, thus allowing gay, lesbian, and bisexual people to serve openly in the United States Armed Forces. It ended the policy in place since 1993 that allowed them to serve only if they kept their sexual orientation secret and the military did not learn of their sexual orientation, which was controversial.
