You make a brilliant plan to assault and destroy an enemy (group, position, ship or aircraft), and then you execute "the plan" which works flawlessly until the first contact with the enemy, at which point, (in the real world), everything goes to s**t, and you must adapt or die.
Ah. Makes perfect sense. I was being dense ... as I suspected.
I think the fact that most of the plans are FUBAR by the end adds to the reality.
