Hero units can be turned into combat machines; for example, you could position Vader as a ballista and have him throw various objects at the enemy. Instead of a tent, you could place that thing from Star Wars Battlefront (the very old one, on the CS engine) – a round object that beeps when you stand near it and heal. And in place of the tent, you could put a similar object from the same game that restored ammunition (a square object that gave grenades and ammunition for heavy weapons like grenade launchers).
