This is because the average width of a division is 20. Thus, from this information, and given the average troop division, the optimal wing size for cas is 60. The maximum number of cas wings that can engage in ground attacks at once is 30. If the cas wing size exceeds the division combat width, the leftover cas aren't utilized, not even in other battles. thus if you have a single cas wing in an air zone, it cannot engage multiple battles simultaneously, only one at a time. The number of cas that can engage in a ground attack is equal to the enemy frontage times 3.Ī cas wing can only engage one battle at a time.
