Who's asking? The draft ended in 1973. Enlistment these days is 100% voluntary. Any comparison to an 19 year old civilian with an AR-15 in his closet and a 19 YO in the military who may be issued an M-4 just isn't worthy of a discussion. For starters, M-4's aren't owned by the troop, they're issued as needed and stored in a secure facility under lock and key when they aren't needed. The military decides when you need them and when you don't. Not anyone can get into the military these days. The requirements are a bit more stringent than filling out a 4473. A NICS check won't get you into the military.
