military

Army 13 years and counting. Like others have said the military is what you make of it. Make sure you read all your paperwork, and if somebody says they guarantee something don't buy it until you see it in writing. If diesel mechanic is what you want I can tell you that the Army has a ton of different vehicles, and a ton of different mechanic specialties. I would shop around with each service and see what they have to offer and choose which one suits you and your interests best. If you want to travel and see a lot of the world, then look at Navy or Air Force and see what they can do for you. I've been a lot of places with the Army but it's usually some third world $h!thole where you go. If you're not going combat arms, look at all the different jobs you can get with each service, and then compare that to what you want to do on the outside and see which one will help you reach that goal. You could get out with several years of on the job training and be set up nice in the civilian world when you get out.
