Got a book on these vehicles. Let me look some things up for you guys.
As already mentioned the Dodge WC 56 Command Car. Duties: command recon. Theres soft and hard cabs for these ones.
Then we also got the White Scout Car M3A1. While being a recon/scout vehicle I'm quite confident this was also used by commanders.
Half-track M3A1, some commanders preferred the US half-track. Patton anyone?
Now thats the US department, nothing really new. AFAIK most of these things where already mentioned. On to the Commonwealth nations 1944.
Humber FWD, it got a really nice command version. Luxury car, almost looks like a civilian car.
Chevrolet 8445-C8 A? Not sure? It looks perfect for command duties though!
AEC Matador also looks really good for this.
And ofcourse the Dorchester which looks the most obvious choice for command vehicle within FH2.
Well thats my contribution to this thread
On a side note: what I would love to see for the Airborne maps is the Cushman 53 Autoglide. A freaking paratrooper scooter, super awesome
