This is all just give and take. If you want to be a fighter pilot, there is a grain of truth to Deuce's post, but that's about it. You WILL put in long days, and you WILL bust your a** to upgrade to flight lead and IP, but the idea we all hate each other and eat our young is absurd. I've been a fighter pilot for 12 years and wouldn't trade any of it. Some of the best years of my life. That said, I'm about to walk away. However, that has nothing to do with the perceived "dog eat dog" world of the fighter guy.
By the time you graduate from Tweets, you'll know what you want to do. FWIW, there are great guys and complete a-holes in every single airframe in the military. I fly fighters and I'm awesome, Deuce fly's MC-130s and he's a complete deuchebag. See?
