Adding a phalanax unit

[Vlad-Tudor]

I would like to add to the Getai an phalanax unit, like the medium ones maybe but I don't know how to mod it into the game.

Edit: I added the unit, but it crashes everytime I try to use the unit in battles. Any idea how to fix this?

I've used the hints from here:
