By itself I dont think the suspended license is going to be a show stopper, it does look bad though. Why is it suspended? DUI ? Reckless driving ? If you got a criminal record with your licenses suspended this would probably prevent you from joining, best bet would be to talk to a recruiter and ask them directly. As you are not even in yet could you get loose of the rank and mosid in youre profile since you aren't a qualified gunner yet.
