A support unit, or a special unit, is an army whose main attack does not rely on the race that you control (Humans, Orcs, Dark Elves) but instead on technology for the humans and magical creatures for the Orcs and Dark Elves. Each group or army consists of 20 to 30 soldiers, but the player is limited to only five armies and a support unit per game.
When the commanding unit enters a battle, the player can control the hero.
Both games deal with commanding large armies in epic, magical battles.
