Hi everyone, i missed my ADSC selection, is it end of the road 4 me?

Did you contact your AFCO as soon as you could, because the best communication with them will help you, and show how eager you are. If you just didn't go then they may just put you on hold for 6 months. The best thing to always do is talk to your AFCO and be honest - show them how much it means to you. for infantry or non commissioned I think you get a second chance as long as you let them know! although 6 months as a penalty wouldn't be surprising.
