I'm fine with letting the halberd militia into the infinite column, but I still think our "elite" heavies should be reflected as being of such a high status by being restricted to a lesser prevalance in the army. I'll meet you half way at 5 for a full stack, 3 for a half stack, as opposed to 8 and 4.

Also -

Just as a historical note, here's the old german titles of nobility and our equivilants.

Political
Elector = Kurfurst
Count = Graf
Duke = Herzog
Prince = Prinz
Emperor = Kaiser

Military
Knight = Ritter
Field Marshal = Generalfeldmarshal
