So you haven't completed basic or AIT? Don't be surprised if you end up on KP or some other lovely detail. Don't get upset because as Rndr said you're not an asset to the unit at this point and if they're going to pay you then they will put you to work somehow (or at least they should). When is your first drill? I'd love to hear what happens.
I didn't realize you could attend drills without being trained but, if that's the way they do things in the NG, that's all the more reason I'd like to hear what they do with untrained recruits.
