That is not an argument, that is a fact. My argument have been stated clearly at #1. You may challenge me for not having any data to support how important of a mobile artillery for USF in team game which should be able to shown by the use rate and win rate of infantry company in team game. But I can't, so I can only tell by experience just like you all.
by ur logic one can do the same for each doc unit, i mean USF has no heavy tank does it need pershing stock ? do ukf need land matrees /sexton stock ? do okw need jli jagdtiger lefh stock ?
do soviet need kv1 isu is2 stock ?
