Movement

While patterns can provide more effective crypsis than solid color when the camouflaged object is stationary, any pattern, particularly one with high contrast, stands out when the object is moving. Jungle camouflage uniforms were issued during the Second World War, but both the British and American forces found that a simple green uniform provided better camouflage when soldiers were moving. After the war, most nations returned to a unicolored uniform for their troops. Some nations, notably Austria and Israel, continue to use solid color combat uniforms today. Similarly, while larger military aircraft traditionally had a disruptive pattern with a darker top over a lighter lower surface (a form of countershading), modern fast fighter aircraft often wear gray overall.
