 Faster Attack
 Build structures that make units (Barracks, V. Factories, etc.), then have each of 
 them to make units. For example, if you made two Barracks and told one to make 
 fifteen soldiers and the other to make fifteen soldiers, both barracks will make 
 them. This works for both IPC and GHOST. This trick will allow you to make 
 soldiers and attack a lot faster.
