Stack Movement?

[Mobhack]

There is no stack movement, and it would need a complete rewrite of the code from the ground up to implement.

All opfire is based on individual movement - which unit of the stack should an opfiring enemy unit fire at?. Would be one such question for example. Or all of them? And if so, how to implement that mechanism.

What movement penalty applies to a stack of say foot and including a tank? Would slower units fall out of the stack?

Basically, you are asking for a total rewrite of a game that did not even originally allow you to stack units (other than when a vehicle dropped its passengers).
