I think a completed FC1 is part of an AD OTS applicant's package, so I bet the OP is going this route.

AFRC used to pump you through the physical process beforehand when they still allowed at-large candidates, but shut that down when they required you to be sponsored by a unit to meet the board.

AFRC candidates: Your FC1 does not need to be done at Brooks. Only MFS does. Just thought I'd toss that out and save you the pain.
