I’m suggesting that the standard salute is rigidly touching one’s right hand to one’s right temple. The British do this palm forward; the Americans do it palm down, still essentially the same.
Still, does any army or even revolutionaries snap to attention with their arms straight out rigid, Hitler style or say, hand over heart.
The Pledge of Allegiance used tolook a lot different.
As a further question for anyone outside the USA, do your civilians formally salute anything?
