During battles, I can deploy 3000 points worth of combined land and air units at a time. I have ground platoon capacity of 2100, air platoon of 2100 and helicopter capacity of 900 for a total of 5100 platoon capacity. But I can only deploy 3000 capacity worth during battles.
Is there any way to increase the amount of units that I can deploy in battle at one time? What buildings do I have to build?
