[quote=@FrostedCaramel]As well I'm also partial to an Air Division but they don't seem as versatile as a Mechanized Division does.[/quote]
I see them more as a modern version of the light skirmish cavalry. They outmaneuver and outflank their opponents, helping to harrass supply lines and disrupting battle plans more than actively engaging an enemy. Useful for both small scale operations, where they can perform hit and run attacks on enemies guerilla style, as well as larger operations where they scout out positions and help force the enemy to keep their forces isolated.

Preferably I'd drop the armour altogether, replacing it with heavy air support or artillery, but given the current options that doesn't seem to be something I can do within the confines of the rules as stated.
