There are many who go into the military just needing to learn a skill, get money for school, or whatever reason. I went in because I wanted to be there to defend the country, which is a different mindset. I don't begrudge anyone for any of those reasons. I was awarded a purple heart, but I would rather have stayed in than receive one of those. It's a very high honor, but I loved my career.
I could rock it when I was a kid. Just buy clothes that look like they are years old in four sizes too big.
