The U.S. Army plans to update the records of transgender service members to reflect only their sex at birth, according to a 14-page internal memo reviewed by Reuters.

“Commanders will take immediate measures to update personnel records and administrative systems to reflect biological sex for all individuals,” the document states.

The move comes as part of a broader effort by the Trump administration to push transgender troops out of military service following a recent Supreme Court decision allowing the Pentagon to enforce a ban on their service.

The memo, which aligns with a February 26 Pentagon directive, asserts that a person’s sex is “unchanging during a person’s life.”

It also instructs that pronoun use “must reflect their biological sex,” and that traditional military salutations—such as referring to a senior officer as “sir” or “ma’am”—should be used “in keeping with good order and discipline.” Additionally, commanders are directed to ensure that shared “intimate spaces” are clearly labeled for “either male, female, or family use,” with access determined strictly by a service member’s biological sex.

According to military data, there are at least 4,240 active-duty and National Guard transgender service members. However, advocacy groups say the true number is likely higher. The Army memo, issued by Human Resources Command, also signals broader changes underway, including revoking gender-affirming healthcare and enforcing a deadline of June 6 for transgender troops to voluntarily leave the service or face removal. The Army did not respond to requests for comment.

“The directives coming out are vindictive and aggressive,” said Jennifer Levi, a senior director at GLAD Law, an LGBTQ legal advocacy group. “At the same time, they are being issued in a chaotic way that undoubtedly is harming military readiness.”

President Donald Trump, who returned to office in January, signed an executive order reversing the Biden-era policy that allowed transgender individuals to serve openly.

The current administration’s stance has sparked criticism from civil rights groups and contrasts sharply with public sentiment. A Gallup poll released in February found that while 58 percent of Americans still support allowing openly transgender individuals to serve in the military, that number has declined from 71 percent in 2019.

The policy shift reflects the broader culture war approach of Trump’s Pentagon leadership. Secretary of Defense Pete Hegseth, a former Fox News host, has publicly opposed diversity initiatives and supports a traditionalist view of military structure and discipline.
