) a surefire G2 LED with a red filter lens. Butane lighter to burn off loose threads on your uniform. Nail clippers. Everything else will be taken from you.
Speak only when spoken to
A Drill Sgt. is not a "sir", so don't call him one.
Start running NOW, every day.
Your not going to Ft. Benning so your not going 11B/C/M ect., so what is your primary MOS going to be?

Just remember, it's all a "mind fuck". I did mine in '83 so I'm sure certain things have changed.
Good luck and drive on, when it's over and you get your little "Thank you for Coming ribbon" you'll never regret doing it.
ps. Then go Airborne and Ranger
