Hmmm, this is an iteresting debate.
I'm a Commissioned Officer in the U.S. Army and while I am referred to as an Officer I am also referred to as a Soldier.
Alot of time we also say "Army personnel" or "Air Force personnel" since we work in a joint office, but we are referring to ALL Army or ALL AF personnel, officer and enlisted included.
We have one Navy Officer in our unit. I've told her on a couple of occassions that the only way I learned their officer rank structure was from watching Star Trek.
(The isigna is the same but the "names" are different).
