It sounds to me like you're looking for info on how to do different types of assessment, one of them being "operational assessment." At II Marine Expeditionary Force, we developed an assessment methodology beginning back in '02 that served us well throughout OIF-I, 04-06, and (hopefully) to this day. Send me a message and I'll give you a point of contact. I believe there are pubs on this as well. Keep in mind that senior commanders should be focused on progress toward major decision points in a campaign, not so much on "combat assessment" of current operations. The commander wants to know if (and when) he's approaching a decision point, especially those that requires either sequel or branch planning.
