Splittertarnmuster or simply Splittertarn (splinter-pattern) was a four-color military camouflage pattern developed by Germany in the late 1920s, and was first issued to the Reichswehr in 1931. It was first printed on the newly designed and issued triangular tent/poncho called the dreieckszeltbahn ("3-corner tent"). Known in German as Buntfarbenaufdruck 31 ("colorful print 31"), for its year of introduction, splittertarn was issued on a very wide basis to practically all regular military (Wehrmacht) units. The pattern consists of a disruptive, zig-zag pattern of hard-edged wood-brown and medium green polygons printed on a light field-grey or tan background. A random pattern of green dashes, called "raindrops", was applied in places to improve the camouflage effect.
