- Air Factory(s)
- Air supremacy
- Tech 1 Engineers
- Land army to keep the enemy at bay
- Knowledge of the Enemy ACU Location
What you need to do is build 10 Tech 2 gunships and enough interceptors to give gunships long enough to take out the enemy ACU. Put T1 engineers on each factory to speed up the process. Then, locate the enemy ACU and concentrate all fire on him. The ACU should die in about 20-30 seconds, depending on the amount of gunships you have.
If Aeon, include Mercies in your strike, allowing you to kill the commander in less than 5 seconds.
If the commander has 4 or more flak near him or is heavily shielded don't try this strategy. Flak kills gunships at an alarming rate.
