It's all lie, the only thing you will get is pain all the fucking day, pain pain pain, you don't have time to eat, time to think, time to sleep and you surely don't have time for girls.
Most soldier that i know now don't have girlfriend/family or are just sociopath.
If you're a NEET just take trade jobs(it's what they're called in america if i remember well) it will be far better than going to a place where you will be broken, bullied and sometimes even tortured (mentally or phisically)
"but but women love uniform" If someone say something like that in front of you please spit on that person. Remember that i only did 2 weeks and i'm already broken, may be worse if you are more socially
