I have to say, I find the A2G effects against targets, effectively useless. The F15E mission "Artillery Pot Shots". I played all day with that thing and different load outs. Unless you get a direct hit, those arty guns will not be silenced. (I promise you. If even one mk82 exploded anywhere near an ARTY unit, they would cease fire and conduct a survivability move. Not that hard to simulate, I would guess)
Further, none of the CBUs (and I tried them all) seem to have any lethality to them at all. I played with burst altitudes, MRAs, fusing; you name it. A2G in DCS on myriad platforms (not just the mud hen) seem to vastly underperform.
DCS is useful for flying and A2A at the moment, but A2G is functionally broken for me, as I prefer the CAS/interdiction role, so combined effects munitions, rockets and guns are my bread and butter. The mk82, 83 and 84 aren't much better. A2G damage modelling needs a serious look, IMHO.
I'm sure ED has had the opportunity to see the effects of these munitions live over the years. I know I have. A T-90 is not surviving a direct mk.82 hit only to have "32% damage" pop up. It would be a kill, combat ineffective or whatever phrase you choose to name. Period.
Just my 2 cents as a longtime lurker/flyer.
