“The DoD is prepared to comply with the court order to access transgender applicants for military service 1 January,” a Department of Defence spokesperson said.
Earlier this year, Mr Trump announced his intention to block transgender people from openly serving, reversing Barack Obama’s move to lift a prohibition.
The change was immediately entangled in legal challenges and denounced by transgender soldiers, and some military officials who said it was needlessly discriminatory.
By announcing a major policy change on Twitter, Mr Trump even surprised some members of his own administration.
Two months later, a federal judge ruled against the ban, siding with current and aspiring transgender service members who sued to halt it.
In her ruling, Judge Colleen Kollar-Kotelly rejected arguments that allowing transgender people to enlist would undermine military effectiveness, echoing a study commissioned by the Obama administration that found that allowing transgender service members would have “minimal impact” on troop readiness.

“There is absolutely no support for the claim that the ongoing service of transgender people would have any negative effective on the military at all,” Ms Colleen Kollar-Kotelly wrote.
“In fact, there is considerable evidence that it is the discharge and banning of such individuals that would have such effects”.
Multiple attempts by the administration to prevent new transgender recruits from enlisting on 1 January were rebuffed in court, including by Ms Kollar-Kotelly.
A Department of Defence official argued that admitting recruits at the start of January would impose “extraordinary burdens on the Department and the military services”.
Rejecting the argument for a delay, Ms Kollar-Kotelly wrote that “with only a brief hiatus, defendants have had the opportunity to prepare for the accession of transgender individuals into the military for nearly one and a half years,” referring to the 2016 directive that initially opened the military to transgender people.
The Justice Department confirmed this week that it would not be challenging those rulings.
