I am supposed to report to Tower School in Sheppard AFB, TX on June 7, but I just saw on my ASK that I had a report date to Ft Gordon on June 10. The school is 3 1/2 months long. How does that report date work? Am I able to report at a later time?

Is your TDY supposed to be in conjuction with your PCS? If so you need to get that report date changed...
