If you lack discipline, self-confidence, and skills, and like being in shape, as well as blowing shit up, being debt free from college, then the military is for you.
The various branches each have their pros and cons but, most things worth doing are hard, and require discipline, patience, an ability to develop a plan an execute it (or at least follow it).
Most guys in the military have a discipline, insight, and a discipline, that many others don't. They know (by training) how to think from the front of their brain, rather than the base. However, some military guys, just like to blow shit up and be bullies (we know what they do when they get out).
The modern military is still boots on the ground, but...now...involves bleeding edge technology that puts those boots further back from the target. (The U.S. military, has, in large part, always won because of its superior technologies developed by the government that have later spun off into the private sector, driving huge leaps in our economy and way of life.)
You may find that being given guidance, and a goal, for a while, being fit, shooting straight, and running fast, as well as learning how to defend both yourself and country could be a very good thing while your acquire adulthood, and valuable skills.
You don't need to think of the military in a gay way, but, as gay is now o.k. in the military, yeah....man..gay guys like to blow shit up, too.
No, doubt, though, the warfare theater is serious business, and...that's part of what you sign up for. You take the good with the bad.
Most military guys I know, have a deep insight, attention to detail, and maturity that you don't find in a commoner. I've known many; I've lost a few.
If you happen to be in, say, The Marines, and are a 50 cal gunner...and witness collateral damage (people being turned to pink mist) you cannot be unchanged. That does not mean you'll be crazy, but, you will be changed...forever. If you aren't prepared for that part of the military, and everyone does Basic Training, then, you should not go.
The Armed Services do much good, but, when an 18 year old sees collateral damage, well, it's not like a frat party......you know. It's serious shit if you end up boots next to target.
Most of my military friends (actually, with one exception, who keeps re-enlisting) have loved the experience; the relationships; the responsibility; the training; the fitness; blowing shit up.
I have one friend who will be retiring as a major here soon. Tim is one of the most cool folks I know, and he understands The Military for what it is, and isn't.
Mostly, it's a job, with no fuck ups allowed. If you can handle that, and wanna get in shape, blow shit up, learn skills, and have lots of friends...DO IT.
