I don't think that's something you can know for sure until you're given the opportunity. As an ensemble musician (i.e. under the direction of a conductor), I'm use to following directions without question in the moment. There's always time for reflection after the fact.
As a bandsman, it's highly unlikely that I'll ever see combat, despite the requirement that I still take training for such. There'd have to be conscription in our country, or something close to, before they'd start sending trombone players to the frontlines. Still, I look forward to serving Canada in whatever capacity is best fit for me to do so, and if that means keeping up morale with supporting services here or abroad (e.g. Remembrance Day memorials, mess dinner occasions), so be it.
You've confused the Navy with The Village People. I still love the unofficial motto of the U.S. Navy, and have made it my own: "Lead, follow, or get out of the way."
