The unnamed whistleblower, the outlet reported, was a "high-ranking officer in the Army Special Forces."
The outlet reported the mandatory program "offers several hypothetical scenarios for how soldiers should be treated if they are transgender or in some stage of transitioning to another gender."
Under one scenario contained in the training guide, a "soldier who was assigned male at birth says he identifies as a female," "lives as a female in his off-duty hours," and "is not requesting to be treated as a female while on duty."
In such a case, according to the slides, the outlet reports that the soldier ought to be "treated with dignity and respect and no further action is required."
If the soldier in question, however, requests at any point to be identified as female during duty hours or appears to be experiencing "increased distress" relating to gender dysphoria, the commanding officer is required to "inform [the] soldier of the Army's transgender policy and recommend that he sees a military medical provider."
"Gender transition in the Army," the presentation added, "begins when a soldier receives a diagnosis from a military medical provider indicating that gender transition is medically necessary."
Another scenario addresses a female service member who tells her first sergeant that she identifies as male and would prefer to be treated as such. The soldier in the scenario has not yet seen a military medical provider for the condition.
At that point, Army leaders are required to inform the soldier that the U.S. military "recognizes a soldier's gender by the soldier's gender marking in DEERs," or the Defense Enrollment Eligibility Reporting System, a massive database that tracks military members.
"The soldier, according to the presentation, will be expected to meet the uniform, grooming, and physical readiness standards associated with their recognized gender," the outlet added, and noted that the soldier in question would then be sent to a military medical provider who is able to determine whether "gender transition is medically necessary" at that point.
A spokesperson for the Army told the outlet that the slides in question are part of a required training and are taken from a program "used to train Army personnel on the recent changes to the DoD and Army transgender service policy."
The spokesperson added that all Army personnel are required to participate in the training by Sept. 30, 2022.
"We remain committed to treating all soldiers with dignity and respect while ensuring good order and discipline," the spokesperson added. "Soldiers who meet those standards can serve openly in their self-identified gender."
