Trans airmen, Space Force personnel have until March 26 to resign under Trump order: Memo

"Service members eligible for voluntary separation pay will be paid at a rate that is twice the amount for which the service member would have been eligible under involuntary separation pay," the memo, signed by Acting Assistant Secretary of the Air Force for Manpower and Reserve Affairs Gwendolyn R. DeFilippi on March 1, states.

However, transgender service members are required to adhere to conduct matching their biological sex, "effective immediately," including in showers, bathrooms and living quarters, until their withdrawal is completed. Physical dress and fitness standards must also match service members' biological sex, the memorandum states. 

Last week's internal Pentagon memo states that service members who are transgender or otherwise exhibit gender dysphoria are prohibited from military service unless they obtain an exemption. 

"The Air Force memo is consistent with this purge of highly accomplished, dedicated transgender service members," attorney Jennifer Levi of Glad Law told Fox News Digital in a statement Monday. "It is shameful. The memo also demonstrates the chaos and havoc being wreaked by this administration in ways that undermine our national security."

Fox News Digital has reached out to the Department of Defense and White House for comment.
