Destroying an enemy base can be difficult because either your bombers get shot down or your bombardment only disable the shields, or your forces are having a tough time destroying the enemies base, well theres an easy way. All you have to do is create an anti aircraft turret near the enemy base and once its done aim it at the base, and since it ignores shields the consortium bases will easily fall. This can also be used to fire at vehicles or the enemy soldiers, I was on the rebels and raided Mandalore with Luke Skywalker, and 2 T2B tank squadrons, in addition I captured the abandoned heavy vehicle factory. I had to destroy a barracks, a tank building, a droidekas factory, and the tall building, along with a few infantry units, and two squads of thos anti aircraft vehicles, so I used anti aircraft guns to destroy the enemy barracks, tank, and drodieka factory, along with 4 of the six anti-aircraft tanks, and one tank from the factory, I ended up winning with everything that I went with. I used Luke's stealth mode to sneak and build multpile turrets. In addition I have used the anti-aircraft guns to destroy numerous rebel and empire bases, along with numerous civilian bases. It won't fail, trust me and your bombers won't be lost, and bombardments can be spared for better times.
