The issue that the Army had undertaken to look at, so far as I know, is the specific problem with this (BS) forensics unit at Madigan "overtunring" PTSD diagnosis. I have had several cases where there were either longstanding PTSD diagnoses overturned in legacy cases, or where the VA exam (in IDES cases) clearly covered all of the DSM-IV criteria for PTSD. I have seen them challenge stressors (even though binding rules have relaxed the "proof" needed for stressors or the reports clearly document the stressors), have seen them acknowledge all of the criteria under the DSM-IV having been met, but then overrule the diagnosis (using this BS device of a "memo of diagnostic variance") using such things as "psychological testing" (often the MMPI or other tests that have problems with them that I could go into a great deal of detail on why they are garbage, but won't here).
So, bottom line, this specific issue seems to be focused on what happened at Madigan. I have had one case returned recently by the Formal PEB (this was before all of this hit the news, but was directly related to the Madigan "events" and I argued it... it was so clear that the diagnosis was bogus that the PEB agreed and sent it back to the MEB...and meanwhile, this issue blew up in the news). All in tall, I think this is a pervasive issue, Army-wide. However, this specific issue that the Army is "addressing" appears limited to Madigan.
