I find it to be a very clever juxtaposition of smoke and mirrors and actual smarts. The formation movement in complex terrain is quite credible and it is not an easy thing to do.
Where I find it to fall flat on its nose is when reacting to incoming fires. Vehicles use smoke but don’t maneuver to get out of the kill zone. Infantry stays put in the open, rather than scrambling for nearby cover or concealment. I am not sure it is a technical limitation rather than a surprising design decision, though.
