Most of the world's military uniforms are green (grass green, dark green or yellowish green). The uniform development of military uniforms toward the green is summed up from the lessons of actual combat.
At the end of the 19th century, British imperialism launched a war of aggression against South Africa. At that time, there was a white nation called "Boolean" in South Africa. They were not willing to be shackled by their foreign aggressors and organized to fight against them. The Boer’s participation in the war is small, and there are many British soldiers. The strength of the two sides is 1:5. The Boer lost in the early days of the war. The British army is self-defeating and arrogant. After a period of observation, the Boer found that the British army had a great feature. They all wore red military uniforms. They were particularly conspicuous in the green background of the South African forest, so the action was easily exposed. The Boer was inspired by it and immediately took his own The garment was changed to grass green and the gun was painted green. In this way, the Boer people used the green background of the dense grass jungle as a cover. The British army could not easily find the Boer, and the Booleans could easily find the British army. They often approached the British army unconsciously and suddenly launched an attack. The British army was caught off guard, but the British army could not find the target. In this war, the British army killed and injured more than 90,000 people and suffered heavy losses.
"Before the car, the car," the lessons learned by the British in South Africa were quickly captured by the army of many countries. In order to better conceal the actions of the army under field conditions, people first start from the clothing, constantly improve the color of the military uniform, and try to make it close to the color of the natural background. In this way, although the forms of clothing in the world are very different, they are gradually unified in the green tone.
Of course, everything is not absolute. From the perspective of hidden camouflage, the color of military uniforms cannot be limited to green. In many cases, the natural background is not green, which requires flexible and reasonable selection of clothing colors based on local background conditions at the time. For example, in the snow, only white can be coordinated with the background; at sea, only blue can be integrated with it; in the desert, only the yellowish brown is close to the background.
