SWC Thread Center of Gravity Construct #82 has Jedburg link to Kilcullen paper that kind of pulls together much of what you all have discussed, very educationally for me. Especially noted that terrorists and insurgents in modern warfare can and do operate in ways that make it important to know, if possible, which one you've got in your sights. But also that the buggers may switch back and forth, depending on the strategic state of play. My first post, beg pardon if someone made this point earlier and I've missed it.
