In my opinion the german army lacks fighterbombers on the normandy maps and only play an air to air role, except some ocasions where they have 1 250kg  bomb if i recall correctly. So why not give some of the Focke Wulf's the Werfer Granate 21. Its a air to surface rocket launcher mounted under each wing. This way the german planes can actualy do something against armor on cobra instead of circling in the air hoping to spot some planes. Im not absolutely sure if it was used alot but it was introduced in 1943. If anyone gots more info on it please share.
