Creating New Unit Ability Formations such as Testudo or Wedge.

[101VaultBoy]

So i'm very familiar with modding, but the one action that eludes me is creating or editing existing formation abilities for units like testudo, flying wedge, or shield wall. I would like to know if any of you other modders know what files/how to change them to create this effect. By changing them I specifically mean changing the units shape, stance, and how close the units are to each other. In addition, changing the skirmish distance would be helpful too.

Cheers, 101VaultBoy

I would also like to know this, as I asked centuries ago with no response.
