The term "splinter pattern" refers to the original German Wehrmacht camouflage designs incorporating geometric shapes with an overprint of rain straits, and to the patterns' descendants. Although the "rain" overprint was a feature of the original German designs, the term "splinter" encompasses all designs that have geometric shapes which resemble splintered shards of glass or other brittle matter. The original German term for this pattern was Buntfarbendruck 31 but it has been referred to as Splittertarn (splinter camouflage) or Splittermuster (splinter pattern) in numerous German sources since the war.
