It is similar to the campaign narrative mode but without a marked narrative and the faction can be selected.
I don't know if we should give it a name to distinguish it.
There is a similar mode in Starcraft 2 as well as in AoE II that serves to improve your game.
"Tactical Command is a basic challenge in StarCraft II."
"The challenge has its focus on teaching the player what terran units to use to counter zerg units."
And it has reward points.
