The standard combat uniform of the IDF has always been khaki or olive green. Camouflage uniforms have been employed from time to time, as needed, by various units but are not considered to be standard issue. The earliest camouflage uniforms of the IDF were donated by France and worn by Airborne troops during the Six-Day War. American-made combat uniforms have also long been in the IDF inventory, frequently worn for training and operational purposes. In the 1990s, a reversible universal pattern was designed for the IDF, appearing first on helmet nets which are in general issue. Oversuits in the same pattern are found throughout the IDF, but again are not universally issued.
