Barely beat rifles,even conscripts can bleed them..some terminators ..lol.This wouldn't be such a major issue if wehrmacht had other infantry options..they don't.So you have 1 line infantry unit for a whole faction.
When people refer to them as terminators, they are referring to the days before the small arms fire changes. This was a time when you could select your 4 man panzergrenadier squad, run into a conscript squad and wipe them out without taking losses.
In any case, you can cut the 1 infantry faction. Indeed they have few infantry, and half of their infantry call-ins are just their regular units in a halftrack, but the ostheer has something the other factions don't have: all support weapons all the time for a low tech cost. With the coming changes to the call-in structure, you can bet your ass that the advantage of cheaply being able to get combined arms and still get tanks in a reasonable time will be very noticeable.
