No amount of buzzwords can conceal that you don't understand what "maneuver warfare" is, either; fourth-generation warfare pretty much is maneuver warfare. Your dilution of your point by introducing United States themes and specific tactical situations makes me question why you're putting so much skin in this discussion if you're as lay as your questions indicate. I'm not criticizing you, for what it's worth, just wondering why you're cloaking not knowing something with extra buzzwords -- you should be happy to learn, not apt to show off.
Terrorism and insurgency are forms of maneuver warfare, and the term "maneuver" doesn't imply scale (and certainly not armor, for that matter). Since you're quite obviously American, the Marine Corps' definition of "maneuver warfare" should interest you:
"Maneuver warfare is a warfighting philosophy that seeks to shatter the enemy’s cohesion through a variety of rapid, focused, and unexpected actions which create a turbulent and rapidly deteriorating situation with which the enemy cannot cope."
That's from Warfighting[1]. Seriously, read up, you sound interested but misguided, and I made a throwaway just to spite you. :)
