HI Blingerman.
I read your old post, and i am a bit confused. you wrote:
''added shield wall to overshoulder phalanx''

AFAIK it is possible to have only 2 formations. So this means you deleted 'square' and added 'shield_wall' ?

and 'overshoulder phalanx' has a particular meaning? are there different phalanxes?
