Stab Pz-grenadier Regt 125, CO/HQ in Kubelwagen, pioneer platoon in S307, motor-cycle combination recce platoon and Pak38 with Laffly tow.
II Batt/Pz-grenadier Regt 125, front right HQ in ex-French half-track with 8 Schwere Ko behind with 2cm Flak 38 in U304, 7.5cm Pak 40 on S307 and 8cm Reihenwerfer on S307. To left, 5 Ko, three infantry stands plus one MMG and four ex-French/Itlian/British truck transports.
6 & 7 Kos from II Batt/Pz-grenadier Regt 125, as 5 Ko above.
So, that should be it for the three KGs as they appeared on D-day, assuming I finish a couple of pioneer stands plus transports for Stug-Abt 200. For completeness, I've yet to finish off Pz Aufklarungs Abt 21, but they only became available to von Luck late in the day of D-day. More importantly, I need to put together the six stands of Pak43/41s for Pz-jaeger Abt 200 for defending the approaches to Caen, the SP Flak 38s and Flak 41s for Heer Flak Abt 305 and a R-Vielfachwerfer on S307 for 10 Werfer Batterie of Pz Artillerie Regt 155.
I'm not aware of anyone making a Vielfachwerfer, so might have to cannibalise a Katyusha rocket launcher to mount on a S307 half track. Alternatively, I might just use a Reihenwerfer vehicle as it would historically provide KG von Luck with off-table fire support.
I think these should be able to keep the paratroopers at Ranville busy for a day or tow.
