What on earth was your motivation for joining the Armed Forces in the first instance?
If you have to question whether or not life on the front line is worth it due to rates and routes then I doubt that you're prepared for the realities of Operations, multis or otherwise. My advice is leave now - your motives do not appear to be the correct ones for a long career spent serving your country. Without such motives, you might find that the 'job' willl quickly become too much to bear.
