I joined up and guess what I did what I joined to do.
Now if that meant being involved on operations which than meant receiving a Campaign Medal great. That was to be recognised for having served in that campaign but again doing what I joined to do. To receive recognition for anything else I would have had to do something that was more than what I joined up to do. For the Americans a Purple Heart for being wounded (killed etc) in action. As much as that was a possibility I don’t think anyone joins up to be wounded or killed.
You join/become a UAV operator that’s what you do. You join up, become a pilot that’s what you do. You join up and become a grunt that’s what you do. To be awarded a medal you need to do something more than you joined up to do.
