I'm sure they teach what reports are required, and when. As well as during turnover the out going General gives a run down of what reports are in the pipeline. That's simple SOP. However, there is no way to adequately prepaid one in a classroom setting for all demands a senior command can demand, especially when what should be tactical in nature takes on a political accent. Unless he was utterly inept at turrning in reports, I don't see why that would become an issue to dismiss him.
