Mike Brunton at CA wrote in one of the Gamespot designer diaries recently, "Invasion is strategic; battle is tactical; deciding where the fight happens is operational."

Can someone enlighten me on the last? i.e. what's the difference between "operational" as used here and "strategic"?

Maybe it's just that I'm coming out of the STW/MTW mindset where the fight simply happens in whatever province landscape the game gives you.
