A DAC is only equivalent to a COL, AC may now be the equivalent of Sr COL and only SAC is equivalent to BG level in SAF.
From the little that I know (the good old days when there was no such rank as Senior LTC in the SAF), I believe that an AC is equivalent to a BG, SAC = MG, DC = LG, CP = General.
Any way, based on a quick review of the SPF directory, there seems to be numerous SUPT and DAC.
