(also known as Flecktarnmuster, Flecktar, Flectar, or simply Fleck)

Flecktarn (also known as Flecktarnmuster, Flecktar, Flectar, or simply Fleck) is a 5-colour disruptive camouflage pattern, comprising black, dark green, grey-green and rust-red clumps and spots on a light green background. The use of spots creates a 'dithering' effect, which eliminates hard boundaries between the different colours in much the same way the squares in the newest digital camouflage patterns do. The pattern is designed for use in temperate woodland terrain. It has been adapted as desert camouflage by varying the colours.

In 1976, the Bundeswehr in Germany developed a number of prototype camouflage patterns, to be trialled as replacements for the solid olive-grey 'moleskin' combat uniform, which is sometimes also nicknamed 'Feldgrau' Field Grey. . . .

Of the patterns tested, that which is today known as Flecktarn was selected for adoption. The word is a composite formed from the German words Fleck (spot or blot) and Tarnung (camouflage).
