It is definitely not a choice to be made too quickly.
You will have to be 'within standards' to join, a certain weight for your height, and must be able to do 60 pushups and situps run 1.5 miles....soon. And those standards do not go away, they seem to get harder and harder (lighter and lighter)
As a computer 'genius' the rating I.T. would be for you, for official training and experience.... definitely good for a 4 or 6 year career, to set you up for a follow on career. the rating used to be a slow way to the top, if you stayed in. Now, computers are VERY prevalent, so it could be improving.
Benefits: for a short career (4-6 yr) G.I. Bill just got a BIG boost $$$$ for college, books, rent....
Again training, certifications, work experience all good for resumes...
medical, covers just about anything,
some elective surgeries, ATV accidents... ~quality~care sometimes, dental etc...
As with most jobs there will be some jack@$$3$ that you end up working for/with. But you can NOT quit, and you can NOT kick their @$$. Of course there will be great people as well, and then they will move, or you will and you will miss 'em
and then you meet new ones... a lot.
How do you feel about boats... BIG ones that do not come home every day, or week , or month.......6 months away from home every 2 years (approximately). But you may get to see parts of the world that most Americans will only see on a screen, some really cool places out there...
If you do not try or get to become an IT, if you chose an Aviation rating, such as AT (Aviation Electronics) or AE (Electrician) etc... you MIGHT go to a squadron that rarely, or never goes to a ship... maybe. Of course even IT people get to leave the ship sometime.....
For a long term career: all the above^^^ and a 20 year retirement plan, that would be EXTREMELY difficult to match on your own.... And lifetime ~medical~care.
Oh, after a few years, you could apply to a program that literally pays you to go to college, then you become an Officer ($$$$ more) and you stay 4-6 years + after college.
Either way: a few years, or 20... it is worth looking into.
Of course the Hair force can offer a lot as well... less boats, more time overseas in places like Germany...etc.
