imo the problem isnt so much the many mgs or the bad us mortar but the fact that each ostheer tier is not only very versatile but also contains some of the most competent units in their respective roles which is turn is helped by the fragility of some of usf key units like the sherman
Meh. I don't find ostheer to be a huge problem for usf in most cases. MG spam can get countered by rifle company flamers in urban maps or by mechanized or just plain old flanking on open maps, or
glorified riflenade launchers mortars if they really spam em hard and don't wanna move. Also, double bars or rangers eat grenadiers for breakfast all day every day (as they kinda should).
