Texas Army chaplain under investigation over Facebook post calling transgender soldiers ‘mentally unfit’ Muri Assunção Army officials are investigating a Texas Army chaplain who wrote on Facebook that transgender soldiers were “mentally unfit” to serve. Maj. Andrew Calvert, a chaplain with the 3rd Security Force Assistance Brigade at Fort Hood, wrote disparaging comments about transgender troops on the Army Times’s Facebook page on Monday. “How is rejecting reality (biology) not evidence that a person is mentally unfit (ill), and thus making that person unqualified to serve? There is little difference in this than over those who believe and argue for a ‘flat earth,’ despite the overwhelming evidence to the contrary,” Calvert, 41, wrote.
