Still the hard edged camo pattern of those Hetzers lined up waiting for guns looks totally different than anything i have seen before.
I disagree that it’s an unusual scheme - ther are a number of images showing this hard-edged style of camouflage
OK, I sit corrected.
I still suspect these were Czech factory patterns that were often later altered by the German crews.
The most common hard pattern has 33% of surface painted in each color with fixed pattern, but the rarer variation has about 10% amount of the lighter color in stripes as wide as a brush.
