But of course the German Blitzkreig, a brilliant archetype of maneuver warfare, overran these emplacements, the fixed system of defense built by the French being the best example (http://en.wikipedia.org/wiki/Maginot_Line).
The US military has been developed for the last 60 years to re-win World War II; even the Cold War was really just the US and Russia building to re-win WWII until Russia ran out of cash.
As one can see given the issues that the US military has had in Iraq and Afghanistan the WWII methods of battle, which have devolved back to phalanx warfare, are struggling (again) to defeat maneuver warfare.
