One of the key aspects of my playstyle is troop transport ships as I call them. As soon as they enter the map, I ground them and have them walk the marines to enemy building on foot across the terrain, without needing to get close.

However, if a building has anything that can hit aircraft, there is a high chance not enough of the troops will make it to their destination. So I got an idea, Tanks.

They would be deployed from a bay at the bottom of an airship or landship like a plane is, and like planes, would be a troop that can't enter buildings but can attack ships, except that it is bound to the ground instead of flying around.

Its goal would be to draw fire from muskets and gatling guns, and will be able to deal light damage to a building with a light weapon mounted to it (like a cannon or gatling gun). Would something like this be possible through modding?
