Speaking strictly from the Army side of things; IAW AR 600-25; SOLDIERS AND CIVILIANS must render "courtesies" during "Reveille" , "Retreat" as a prelude "To The Colors." On Army posts ALL vehicles stop and persons render honors etc! In my 26 (active and DoD) years of service, I've never heard (on Post) the National Anthem played after "Retreat" or "To The Colors."
I'm Air Force so I can't speak for what's played on post. Just the Air Bases I've been to.
