I don't personally see the need/desire for this to be able to go to the field. That is what aide memoires are for and the Combat Team Commander course provides a pretty hefty one.
Old Sweat's comment about having the experience is more important than having sound doctrine made me think about when we were digging through PAM after PAM trying to figure out the defense... how all this institutional knowledge had been lost and not written down anywhere, and now we needed it... we didn't have any true experience to draw on, and neither did the institution as a whole, not that we could find anyway... so we *had* to fall back on the doctrine as a start state. We were looking for things as basic as how to do range cards, which 20 years ago I'm sure no one would believe could be forgotten.
We can't predict the future... we don't know if the next conflict is going to make us ignore this basic stuff for 5, 6, or 10 years... I'm not saying we're experts at combat team operations now but imagine if we didn't touch conventional combat team ops for 10 years because we were focused on a different style of warfare or different threat that consumed all our resources for that time period (like Afghanistan did)... and then 10 years from now, someone needs to dust off the books and get back into this... what will the book they dust off tell them?
Hopefully more than our current pubs told us about defensive ops...
