I wish you were right, but that's not so in the US.
As a former serviceman, law and military regulation permits me to render a military salute to the flag and anthem of the United States or to those of countries recognized by the United States while in civilian clothes.
However, US Equestrian Federation dressage rules permit only military and police personnel in uniform to render a military salute. Men must either remove their hat and lower it by their side or perform the same salute as women.
I've come up with kind of a hybrid from the days of top hats: touch the brim of my helmet as if to remove it in salute, then slowly drop my hand at my side and incline the head. It feels more proper than just imitating what women do.
