YARTS will eventually have many different unit types, as the architecture makes it simple for us to create them.
The current list of units is as follows (not all of these may be available to the player):

	Hoverjet Fast, light, manouverable unit, armed with twin machine guns, each with a short range.
	Tank Medium speed, medium armour unit, armed with a single mid-range cannon.
	Artillery Slow, heavily armoured unit, armed with a single powerful long-range cannon.
	Sheep Passive units that do not (yet) contribute much to the game. They tend to wander away from other units, and are only found on grassy areas. They also have a nasty tendency to explode on contact.
