In a 1954 issue of ” The Quartermaster Review,” Major A.M. Kamp Jr. wrote, ” the soldier, being constantly confronted with the debauching of his uniform…soon loses pride in wearing it. His prestige is gradually being degraded because of the contempt shown the uniform. Since 1946 this has been one of the biggest stopgaps to the adoption of a new uniform for the Army. Prestige and morale, the basis for building and maintaining a spirited, well-trained Army, have suffered as a result, in addition to the fact that the Army apparently has no exclusive rights to the wearing of the uniform.”
This was because during WWII, the Army had more than 8 million active duty personnel. In 1945, that was almost 6% of the population in the United States. After the war, veterans and non-veterans wore the olive drab army uniforms due to the availability and low cost. The olive drab uniform became work wear and was even reissued as prisoner gar throughout the US federal and state prison system.
The army green uniform became the official uniform of the US Army the year after the Korean War armistice was signed.
