Morale Booster: Friendly units in a certain area get a rate of fire buff and survivability buff, or maybe only rate of fire.
I thought of Dawn of War: Dark Crusade, where the Imperial Guard gets the Commissar who kills a soldier and then everyone gets a morale boost and fire of rate boost. But maybe take away the killing part, i would hate to be picked as that guy.
Or that could add a new realm of gameplay, whoever performs the worst will be executed to make everyone better, so everyone will want to fight better incase they get chosen to die.
