Jrow,
I can help some. I was 13 years in AFSOC, weapons & tactics background. Very familiar with those organizations & missions. Two friends have been 6th SOS (the active-duty FID/CAA squadron) commanders.
The 5th SOS used to be a straight AFRES MC-130P COMBAT SHADOW unit, then became a reserve associate, and then about 3 years ago, transitioned completely to the U-28 and FID/CAA mission. The AD 6 SOS has been doing the mission for a long time now.
PM me with an e-mail address and I'll send you a SOF primer that explains the mission in great detail. About 5.5 MB file.
