This is taken directly from DoDI 6130.03, dated April 28, 2010. It is still current, at least as far as I can tell from the DOD websites I can access.
These are the DQ items.

If you do not meet the requirements of DODMERB for accessions, they will DQ you. You must meet the minimum standards for entry into the military.
If you did not meet the standard however the SA decided that they wanted a waiver, and the AF surgeon's determined that a waiver was possible and allowed one, then you could be cleared.
I won't sugar coat it; if you are outside the standards, it will be a very tough road.
