I'm pretty sure you can't implement this: Fc06.deviantart.net
But I have an idea. It could be 3 tanks that are forced to follow one another, or just have the double 156mm cannons as the main gun and have the others programmed as MG's (like the Maus in NHC mod, which has a very heavy MG cannon), or just implement the two together.

Mainly play CoH on NHC mod. Fairly good at it.
