Ok here's your heads up don't join the military as in ground troops unless you plan on being shot at and bombed ect. I once thought i wanted to go to the military, so I researched it, not necessarily online but with family and friends ect people you can get a trustworthy opinion for and here's what I heard.
In Iraq (for americans) the military had to deal with things like road bombs and were actually getting shot at and dying and such, Vietnam military we were dying infact we were bombing our own ground troops on occasion and so far so forth. Don't get me wrong thousands of ground troops And survived in Iraq but thousands also died.
However, if you do feel that you need to join the service I might suggest looking into something a bit further away from the field of combat, there is a lot more perks in the Navy, The Air force, or if you really want to join the army you could go to college and join there automatically in a higher position. Basically what I'm saying is research it before jumping into combat you might find better choices more suited to your needs.
Also If you pay taxes you can be drafted well unless you weren't born in america and I think you can get out of it Via religion, schooling, or medical issues.
I hope i didn't offend anyone with this post don't get me wrong ground troops are a major part of the fight and they are very well trained. I just don't want anyone to think I don't appreciate and support our troops.
