While we are on the subject of authenticity, I just thought I would add that the Panther D, and not the A, was actually the first sub-type used.
I know it goes against common sense, but for reasons that are still not explained entirely, the D actually appeared before the A, then of course the G variant came.
The only explanation I can think of, is that seeing as how there were numerous problems with the initial Panther (e.g. too much strain on suspension, flawed mantlet design, etc.) prototypes, the designers quickly tried to address issues, and the result was that they said "well, this isn't really the first Panther anymore, seeing as how we added a bunch of extra armor to the front, changed the suspension, geared the engine differently, blah blah, all at the last minute, so its actually the 'D' series" But then shortly thereafter, when the problems in the design were ironed out, the thinking was probably that "Well, those first models were produced hurridly and in limited amounts, so we were maybe a bit hasty calling it the 'D,' lets just start fresh and say we have our first, definitive 'A' version..."
The G was similar to the A, except the slope of the armor was increased on the sides, to about 55 degrees or so if I remember right, and there was a different cupola arrangement. Of course, both the A and G differed from the D in that the "pop-up" hatch for the driver and bow machine gun were replaced with a standard hatch and ball mount, respectively, not to mention the numerous other little changes that made it a better tank all around, like fixing the mantlet chin.
BTW, I also think it is appropriate to have the grey scheme with the Panther, but this would have to be very early in the Panther's lifespan. Most Panthers that were first field tested had a plain camo scheme, and in Italy, a few were rushed so quickly to the front that they were in this "prototype white" scheme.
But yeah, definitely on any late 1943 or afterwards maps, the Panther and Tiger will need ambush schemes.
