"Striker, this is HQ, engage the enemy at (357|580), over!"

Now that there are elements controllable by the player, they should interact with each other. This means there should be the following features:

• Elements can see x tiles far and by that detect other elements
• When an element is hostile it is being engaged
  • This means the attacker maybe has to move into fighting range
• When an element "dies" it is being removed from the map and the engine
