I think he meant playermodels with equipment. How silly they would look in desert with those happy green clothes
North Africa is a Medditerranian climate, not desert like Lybia and Egypt. They even get snow. So green uniform's aren't THAT bad (I should know, I live in the same climate, in a region called Los Angeles
).
But yes, playermodels and etc would remain same. Only thing would be reskinned tanks, the Lee, and the 37mm AT gun, plus the 37mm AT mounted on jeeps.
