I heard through the Army grapevine that Maj. Gen. Jeffrey Schloesser chose to retire because the company, battalion and brigade commanders were given GOMRs (General Officer Memoranda of Reprimand) in the Wanat matter, but he wasn't, and he considered that unfair. (He had been the overall commander of U.S. troops in eastern Afghanistan, which is where Wanat is.) So I sent him a note to ask him if that was accurate.
Yes, he responded, "That's correct."
