Lol. The Corps is so different than you could ever imagine, you have no idea what you're talking about. Best of luck. If you get into CAAT, you'll at least enjoy your actual job and being in the field more, however actually doing the job you signed up for is less than 1-2% of your life. Most of your time will be spent attending briefs about suicide prevention, violence prevention, alcoholism awareness, about how not to get in trouble, about nothing, etc etc etc. You'll spend a lot of time trying to get a site called Marine Net to work, which seems like it was made in the 90's and only barely works on internet explorer, so that you can do mandatory annual training about above said subjects, you'll spend a lot of time printing out useless papers from said site about nothing. Lots of time showing up to things pointlessly early so you can wait for about an hour for your higher ups to show up, to stand in formation for about half hour, to then be told nothing by said higher ups, then leaving, and having to rush back for another pointless formation. You'll wait around every Friday until about 1630 for another, even larger formation, to get the same safety brief from 3 different people in your chain of command before you can finally get cut for the weekend. You'll more than likely have some insane libo policy that will make you feel like less than a child. You'll spend more time standing by than you will actually doing things, and until you're an NCO, the things you'll be doing will be supervised by someone who can barely read. This is only a fraction of the useless insanity that occurs, I'm not even going to try to scratch the surface of all the useless bureaucracy and broken systems in place.
But hey, what would I know. Go ahead and email this to yourself though and reread it in a year. You'll be blown away at how much it will hit home after some time in the fleet. Best of luck though, not trying to talk you out of it. It's not all bad, just 99%.
