Build 25-50 desolators depending on the size of the enemy base when you have enough money. Group the desolators in groups of five and put them in teams. Take them and deploy them around the enemy base. Now the enemy will not be able to leave their base. The enemy will not be able to attack you in any way because all their units will die. *Note this does not work as well with apocolyse tanks due to their heavy armor. The enemy will now be forced to leave you alone and will not be able to mine ore! *Note this works better if you gaurd them with a couple terror drones. *For better results add more desolators.
