Much of Europe is mountains and they often have snow on them. Being able to fight in those conditions requires special training and special gear. In WWII the Germans had divisions with just those qualifications.
These are the regular uniforms found from the Mediterranean Sea to the Arctic Circle. Germans landed small parties along the coast of Russia and Norway and Greenland to predict the weather and they wore uniforms much like these troops.
As usual this Caesar set is flash free, the figures are highly animated and the poses are great! The set includes this officer figure with binoculars, a light machine gunner who is firing from a kneeling pose and two grenade throwers. The old Airfix set is totally outclassed by these troops, although the specialized mountain climbing, bike riding, and mule skinning guys from that set will still be useful.
