I want to be the one to point out that retired generals making political statements is heavily frowned upon, so for them to take a step beyond that and ENDORSE A CANDIDATE is practically unheard of except in fringe cases like Michael Flynn.
Upper brass is a pretty exclusive club, and retirees don't generally make political statements to avoid stepping on the toes of the currently serving generals/admirals. If multiple generals/admirals felt the need to take this step, they would've done it with the knowledge and consent of current leadership.
Yeah, if I were Vlad, I'd find a way to magic myself up a nose; he looks way better with one than without.
