Hi @m30wm1x there are a couple of things I’m going to throw in here as a caveat.

Thing the first, very roughly for historical units a lot in the netherlands had been sent there after coming from the eastern front, I’ve not dug into it massively to get exact numbers as there were a lot of Kampfgruppe formed, but if they were at Caen they probably didn’t end up in the low lands. I’m sure others with better knowledge could probably tell you exactly who is where and when. So I’m going to give you a balanced force based on what I would add to hit the beach that is fairly accurate but won’t be a match.

Thing the second, I haven’t picked up the D-Day book for the Germans yet with the expanded choices, so I’m building the list based on the basic fortress europe lists. Points should be the same and you won’t really be missing out if you buy anything on this recommendation. But I would suggest getting the D-Day: German book.

Now list time, 51pts from hit the beach you say. So to that here’s what you could do.

5 StuGs run as 1 HQ and 2 platoons of 2 = 28pts, run as a separate formation.

if you pick up 2 boxes of halftracks you can run the infantry as Mechanised Pz Grens

I would certainly suggest Nebelwerfer, 6 if you can, they are your best bet for dropping smoke and pinning dug in infantry

it leaves you 10-12 pts, bulk out the StuGs and then maybe look into an aircraft or anti air for some variety.

I would suggest the stuGs first as it puts you around 75 points, so you can start playing with the 50 you have, push up to 75 pts and then grab the last bits and pieces to reach the 100 once you’ve seen how it plays and if you need something in particular to help you balance more against your regular opponents
