1LT (Join to see) you'll need to take your hand dandy CAC card and spend an afternoon going through Combined Arms Center. CALL, ATN, CARL and other resources are out there to capture these types of products.

Select products and resources. CASCOM has a thing called the one stop where links to every SRC MTOE to the doctrine publications, METL, and TTP manuals. I no longer have a CAC so I can't drill down into these.

Well you might ask a Scout (19D) about Zone, Route and Area Reconnaissance.
