To Attack Faster
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.
