Massive scale RTS

Hello there,

I'm looking for an RTS game where the scales of battles are just ridiculously big.
Basically, something where we send swarms of thousands if not millions of unit on the battlefield.

Basically, If Ultimate Epic Battle Simulator was an RTS it would be the game I'm looking for
Does anyone know anything close to that?

I don't mind poor graphics, that's usually a given when we're having so many units.
