Military uniforms have been in place ever since the very first overall desired his troops to seem imposing and cohesive about the battlefield. Costumes have been away for each of the soldiers to appear the same, and so feel more united as a group. Modern militaries usually stick with this approach, also for a lot of the very same factors. By mainly stripping incoming recruits of the individuality, army uniforms cause the rookie to see their identity among the cause, rather than their own.
A superb example of one of the first instances of this mismatch in uniform plans is that the American War for Independence
The British, with their red coats and white, crossed sashes lined up and fired coordinated volleys in the woods, although the Minutemen with their drab, buckskin clothes were able to hide and shoot from behind cover. Uniforms with a more drab, ordinary appearance became more widespread amongst standing armies at the first World War when trench warfare and machine guns made the head on war all but hopeless.
Today, many militaries have more than one uniform for troops
A formal, perhaps brightly colored dress is for official functions during times, or places of peace, when no fighting will happen, along with a drab, durable uniform is for practical application in the field.
