I scored an 88 and the marines, airforce and army all told me the same thing. "With a score like that you can pretty much pick any job you want in the military" with maybe an exception of a couple, so if your getting 90-95 your set for any branch you want. The pay isn't too great when you first start out, and you need to WANT to be in, or else you'll regret it. Don't do it for the wrong reasons even though I'm not sure what those might be, maybe doing it under the impression it will be a easy way to pay for college. Oh and one MAJOR word of advice, if you're going in, either go full out, or not at all. Don't do reserves. My brother is in the National Guard on reserve and it made his life a living hell when he was trying to do college while in. Don't listen to their lies saying how you can be in and go to college at the same time while on reserve. He would get through a year of college, and then they would ship him overseas, then he'd come back, and have to get back into the swing and before you know it, your sent back out again. He's being deployed a third time, and still hasn't had enough stable time over here to get his degree, it's looking like another year of school to get the credits needed. So either go active duty or not at all.
Also make sure you are REALLY clean for the drug test. They send it to a lab, and I hear people being clean for over a month are still failing, if they pick up any trace they'll send it to be tested more thoroughly, and then again if it comes up a second time, the third test is like 99.99% accurate so you better have EVERYTHING out of your system really good.
But don't get me wrong, I'm in a military family, and in a military area, not one person regrets ever joining. Times might get rough while your in, but it's a life experience like no other that not a single person I've talked to (and I've talked to a lot) ever regrets. The skills you'll learn along with things like self motivation, respect and discipline will last you a life time, and if you don't blow your money and live on base you can really work up a good cushion of savings from even four-eight years. There really is a good chance you'll be sent out though, even doing non combat jobs like working on an airplane or something. You may not be in the country, but if your doing jobs like that chances are you still won't see combat so if that's what has you questioning I don't think you should be worried. Really the best thing I can say is go talk to a recruiter for EVERY branch unless you know for a fact you don't want to join one. They each offer good benefits and all have something to offer and hey, maybe you'll find something that peaks your interest in the coast guard, you never know.
Edit didn't read all the post, my bad. It looks like your looking for active duty which is great and already talked to the coast guard lol.
