Arguably games like StarCraft include operational elements - managing and defending the peon line is as important as the front line.

It's still merely tactics though.

I'd say that managing your rally points and reinforcements (for terran, mostly) is the only thing that is related to operations, and it's a pretty limited part of both the game and what operations is about.

A lot is about predicting when you will need which size of army and preemptively build the right size of production to be able to produce that, just in time.
