Those odd Eastern Bloc camouflages.
Have you ever noticed how some of the mid-Cold War uniform camouflages seem to have little actual camouflage value?
It came out of a German, I don't know if it was Second World War or East German, study that showed that solid colours were better for moving troops. Evidently "busy" camouflages draw the eye if the soldier is actually moving.
The Germans thought that the individual soldier was more vulnerable when he was a fleeting target and quickly moving from position to position and as such created the various "rain drop" camouflages that they considered the best compromise. When the soldier was stationary they were to use fieldcraft to avoid detection.
As friends who served in Afghanistan have told me that people wearing literally black and white blocks of colour can disappear into the terrain it might have had some validity as a concept.
The Russians were never convinced though and adopted a variety of more conventional blocky style camouflages.
(East German and Polish uniforms for examples. Note that the Polish first echelon troops had a different colour camouflage in the T2K setting)
