No its different papework, I can't really remember exactly, boot camp is still a blur, lol. I know you fill out your GI bill paperwork, well with the new GI bill you might not even do that anymore. You also fill out your next of kin, life insurance, and well basically your first day and a half is almost all paperwork. Oh and you want to know the most awesome thing about this paperwork deal??? Well after this you go meet your Senior Drill Instructor, and later that night you get to do something called sleep, and trust me that rack will feel like a double stuffed feather bed! Then like 6 hours later you'll wake upt to a morning that will seem like hell, and you'll wanna go UA, lol, just remember this phrase "lights, lights, lights".
And no infantry does not require a security clearance.
