Even as the new guy to the squadron, you DO have something to prove. Those that have been deploying look at you as the green new guy that doesn't know anything, and it will remain that way until proven otherwise. That being said, until you have MWS experience, you will probably continue to be treated like you don't know anything (because you don't). But once you're finished the FTU...
Like said above, shut up and never, even whine. Its really annoying to listen to someone in our field go on and on about how much their job sucks.
Study, study, study. Being the best copilot/wingman you can be will earn you alot of ground and get your name around the squadron.
Don't ever tell anyone how good you are/were. If you really are, they'll know.
