I was a Marine and I did a lot of Technical stuff. To the OP, find out what you want to do? Active duty, reserves? Do you eventually want to become an Officer? I wanted to be a badass Jarhead when I enlisted, so I went for infantry. It took me seven years as a grunt to find out I can do Communications real well. Only you can figure out what you want? But when all is said and done, get it in writing before you sign. That way you have proof and and it will give your senior enlisted personnel some ammo to fight for you to get what you are entitled to. The only thing that can trump that is time of emergency when needs of the service branch you decide to go with outweighs personal needs. But in that situation everyone gets hosed.
