Say your the empire, and the rebels have a very strongly guarded base, with a well defended sheild generator. So you send a small force at their base and after a few minutes of battle, you pull them out, hopefully pulling the rebels out with you. Then from the flanks you drop down reinforcements and attack and undermanned base right when you do this you also turn you other force around and send them right back into the pursuing rebel forces. With some help from a few hidden AT-AT's. How do you like it.
