Do you know why camouflage uniforms are worn in the army?

Camouflage clothing is a clothing with irregular protective color patterns composed of green, yellow, tea, black and other colors for camouflage. Since there are a lot of field operations in the army, in order to better cater to the surrounding environment, we use camouflage colors to camouflage ourselves and fit in with the surrounding environment.
The camouflage uniform requires its reflected light waves to be roughly the same as the light waves reflected by the surrounding scenery. It can not only confuse the enemy's visual reconnaissance, but also deal with infrared reconnaissance, making it difficult for the enemy's modern reconnaissance equipment to catch the target.

Camouflage uniform is a basic type of training uniform. 'Camouflage' is a new type of protective color with irregular patterns composed of green, yellow, tea, black and other colors.

Camouflage uniforms appeared very early as camouflage uniforms. Hitler's army first used camouflage uniforms at the end of World War II, as 'three-color camouflage uniforms'. Later, some countries led by the United States were equipped with 'four-color camouflage uniforms.'
The US Army: In order to improve the versatility of camouflage, a process of printing and dyeing multiple colors on both sides of the fabric has been specially developed for its training uniforms. One side is printed with a standard forest land pattern and the other side is printed with a three-color desert pattern. It also developed a special camouflage pattern for its chemical protective clothing.

Chinese People’s Liberation Army: The camouflage training uniforms are divided into summer and winter (07-style camouflage uniforms). The color summer is a woodland four-color camouflage pattern
The color of desert grassland in winter is common to all three services. At the 70th anniversary military parade held in September 2015, the multi-terrain camouflage uniform made its first public appearance

Japan Self-Defense Force: Camouflage uniforms are available in spring, summer and autumn general categories. They adopt thin-line four-color camouflage and two colors, and use fabrics that are equivalent to the infrared radiation of the environmental plants in the season.
For winter camouflage clothing, a white blouse made of a single-layer fabric with the same ultraviolet reflectance as snow is put on the surface of the autumn camouflage clothing. The inside is equipped with kapok undershirts, sweaters and cotton clothes, which increase moisture absorption and warmth, even at minus 30 degrees Celsius. It can also play the ultra-high performance of 'waterproof and cold protection' under high climatic conditions, and can play a good water and wind resistance.

The German camouflage uniforms received very good results in actual combat. Later, the military of various countries followed suit and studied and improved the color and patch shape of the camouflage.
The camouflage uniforms newly developed after the 960s are made of synthetic chemical fibers. Not only are they superior to the original cotton material in terms of anti-visible light detection, but also because the color dyes are mixed with special chemical substances, the camouflage clothing’s infrared light reflection ability The reflection ability of the surrounding scenery is roughly similar, so it has a certain camouflage effect against infrared light detection.

Nowadays, camouflage is not only used on soldiers' uniforms and helmets, but also widely used on military equipment such as military vehicles, artillery, and even aircraft.
