Battalions and Combat

Combat is fully automated and happens on either a 12 x 12, 24 x 24, or 48 x 48 Combat Grid. Units take up 1-9 spaces. Combat grids can accommodate between 2 and 8 battalions.
Battalions can take up to 40 total spaces each, and spread out as much as 10 units wide and 4 units deep.
Each Battalion moves forward one row at a time until engaging an enemy. Then each unit uses pre-programmed techniques simultaneously per block until all units of one side are defeated. Then the battalion will move to engage the next enemy battalion.
Combat can be one side versus another, free for all, two against one, four against two, or any other combination. Alliance status of owning players affects battalion allegiance. Neutrality is also an option.
