If I refer to someone in the military as a soldier, I am not *wrong* even if they are in some other branch of the military than specifically in the army.

I may be imprecise, but not incorrect.

That is a matter of opinion. As far as I am concerned, you are wrong. For me, "soldier" only means someone in the army, not any other branch of the armed forces. The imprecise nature of the information leads to confusion and, thus, fails the basic requirements of communication.
