Mechanized Infantry should have the shock of Armor

I have been playing board war games since the 80s. Including Gulf Strike, Third World War, Squad Leader, and others. In those games Mechanized Infantry are considered hard and produce shock similar to other armored vehicles. In CON mech only gets a fast speed and a couple points higher attack and defense, however i think this can be improved. The simplest improvement is to enable shock on the Mech Infantry in the Infantry research tree. A more advanced would be to change to the Mech Infantry to a vehicle similar to an AFV object when its attacking or moving.
