I picked the 'never served' option. I spent my senior year of HS in NJROTC, because of my Asvab and Nuc field entry test, but I decided that I really hate Calc, and went to college instead. My dad and an Uncle both spent time in the military, (my dad was only in a very short time, my uncle career) and for at least 2 generations back on up the paternal line, the family fought in some war or another. Though, near the end of my time in college, I did consider applying for a military job working with mapping and cruise missiles. (Don't know much beyond that, it was a Boeing job posting that was up for a while.)
