The Air Force is the only one of the military branches involved in President Donald Trump's mandated border mission to not disclose publicly the number of service members or what units they're coming from.
Same thing they did when beating up and shooting BLM.
Edit: It’a really hard to find any report on the events during the BLM protests. I distinctly remember many mentions of the LEOs involved in shooting “rubber bullets” at protesters and beating them not having any identifying information on them. No names, no agency tags, nothing.
