IIRC, the genuine documents released by Bush contained the so-called bogus reference. The reference is to a real section of the AF manual, it presrcibes the penalties for failing to follow an order, but does not prescribe the regulation that mandates the medical examination.
I can imagine the DNC using that reference, and in an incorrect way. Lots of DEMs have been fixated on Bush's records, and attempting to fill in the gaps that would make a "slam dunk" case against Bush's TexANG service.
Go to this site they completed an excelent research:

I could not find AFM 35-13 listed anywhere. Where did you find the reference to the AFM 35-13? Other than Bush's docs.
