I think this as a bit more than nit picking. why I hear you ask?
First the grenadier coy with a MMG in each squad and the grenadier coy without rifle squad MMGs play very differently, ie firepower and mobility are worlds apart.
The Protze has a much better cross country abiltiy than the Opel. This is important when the grenadiers are trying to follow tanks. Not to mention that if the protze was used the grenadier coy would now have effectively 6 rather than 3 squads very different to what we now have ie a lot more flexable.
From the link below we also see that Grenadier coys were also mounted on bicycles and in 250s. Adding the bicycle formation into the game would I think add a lot of interest, and keep the germany had no petrol or equipment players happy.
Lastly is seems there may only be the one reference supporting MMG rifle squads, everywhere else (I can find) says MMGs restricted to the support coy.
So where we now can choose betwen Opel or 251 we would be able to choose Opel or 251 or protze or bicycle or 250 mounted coy.
For completeness sake Ill drop this post in here also
Looking at The link Clause supplied
It would appear that maybe shutzenpanzer has suffered in translation or that this is a typo.
There are several grenadier TOES this one in particular
details the protze mounted grenadiers as described in Bayonet.
Also I have looked at I think each grenadier formation and yes these TOEs do show the rifle squads carrying 2 LMGs and the tripod MMGs restricted to the Support company. This is also the case in the one book I have "german tanks and fighting vehicle of WWII" ISBN 0 7271 0006 8 and pretty much anywhere else on the internet I can find.
The LMG interpretaton makes sense to me as
Obviously a company assault would be impossible to coordinate using this number of MMGs.
All the extra tripod MMGs would only really be useful in prepared defensive positions. So the rest of the time the tripods wouldnt be of much use. This would be a bit wateful as they were very expensive to make (much more than the actual MMG) not to mention training a gun crew in each squad only to 'waste' them as LMG operators.
The normal infantry battalion only had MMGs in the support Coy if this formation was good for the infantry why would the grenadiers need a MMG to be assigned to each rifle squad as well? seems far too generous an allocation ie very top heavy.
Apologies for the tedium Chuck.
