In the beginning there was Command and Control Warfare (C2W). And the US military said it was good.
Then we had Information Warfare (IW) and life was good.
Then in the mid 1990s we got politically correct and called it Information Operations (IO), because State doesn’t DO anything associated with warfare. And life was good. In the latest edition of Joint Publication 3-13, Information Operations, the official acronym IW was dropped by the US military.
