Camouflage Shirt: Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see (crypsis), or by disguising them as something else (mimesis). Examples include the leopard's spotted coat, the battledress of a modern soldier, and the leaf-mimic katydid's wings. Military camouflage shirt was spurred by the increasing range and accuracy of firearms in the 19th century. In particular the replacement of the inaccurate musket with the rifle made personal concealment in battle a survival skill. In the 20th century, military camouflage developed rapidly, especially during the First World War.
On land, artists such asAndré Mare designed camouflage schemes and observation posts disguised as trees.At sea, merchant ships and troop carriers were painted indazzlepatterns that were highly visible, but designed to confuse enemy submarines as to the target's speed, range, and heading.
