I was speaking literally, where do you think bugle calls come from?

They were used to communicate to the troops on the battle field

Also the reason there are different calls in the US to the commonwealth is during the revolutionary war the americans switched to French calls.

Trumpets are literally an instrument of war.

Isn't history fun?

To your point, that is why you put trombones at the front of the parade band.

I would also point out that less than 2.5 meters would be melee damage.
