I don't know if there's really such a thing as a typical everyday life of a Marine Corps pilot. Maybe somebody else can elaborate on that. As far as daily time commitment? If you're worried about that, then maybe you should consider another line of work. Seriously, not to be a dick, but aviation (especially around helicopters) is extremely maintenance intensive. It is not at all uncommon for maintenance crews to work around the clock. Sometimes it can be split into 3 shifts, sometimes 2 shifts, or you can end up on what's called "Day crew-stay crew". That's just for maintainers, though. Aircrews are limited by "crew day" where they can only work a certain number of hours per day if they are flying. Somebody correct me if I'm wrong here...that can be waived at the CO's discretion, right? If they aren't flying, though...
As far as how do you handle deployments? There will be people who try to help you out (family services center, legal office and such) before you leave. Otherwise you just try to scam as much time at home as possible then call and email every chance you get while you are gone. Letters are nice too but who writes anymore? It's weird-being in college is the first time since I've been in where I haven't watched the evening news to find out where I'll be going next.
How to handle what people think? I'm sure others will tell you their stories of how they comforted their families and what worked and what didn't. My wife supported me and that's all I needed. You're either with me or against me, right? I'm not trying to get a commission because my high school buddies think it's cool. And those assholes out there who called me a traitor for leaving the SNCO ranks, well, I don't care what they think. If you support me, I love you. If you don't, take a hike. In summary, my take on that issue is that if you always worry about other people being happy, other people will be happy instead of you. Do it for you. Good luck.
