From my reading of Luttwak and others defense in depth is a static strategy. Maneuver warfare and insurgency would seem to be counter strategies to a defense in depth approach. Whereas, war by attrition isn't a strategy but a comprehensive environmental condition. Suggestions? Specific readings? I'm looking for military tactical and strategic examples on how to counter defense in depth. In the information realm the "advanced persistent threat" or "crippled caterpillar" attacks are useful.

Thanks!
