M.L.,
There is a paper I posted on here a few years ago that deals with this subject. I am trying to find it and will post it again when I do. Here is the short version. General MacArthur supposedly said Strategy "Is Maneuver of Large Scale Forces". The paper goes on to point out that Maneuver dealt with the selection of the battlefield and the movement to the battlefield. Once you got to the battlefield (within range of the enemies weapons) you were at the tactical level of war.

Enter the ICBM... that changed everything because there is no place on earth that can't be hit by a missile, so the new idea was that Maneuver (operations) no longer truly existed, everything had become Tactical.... guided by Strategy (battle command). Some even thought that Strategy no longer even truly existed, except at the Political level.
