U. S. ARMY COMBAT UNIFORM

The United States Army during the inter-war period followed the previous model of having a standard uniform that combined elements of both the Class A (basic service uniform) and Class B (basic field uniform). By combining the uniforms, it was thought that time and money could be saved. Included in the clothing system was an olive-drab (OD) wool garrison cap, olive-drab wool trousers, an olive-drab wool spread-collared shirt worn with a black tie, an olive-drab wool four button tunic, and russet brown Type I (leather-soled) or Type II (rubber-soled) service shoes. An outer jacket or coat, either the Model 1938 "Overcoat, Mackinaw, Roll Collar" or the Cotton Field Jacket[disambiguation needed] in Olive Drab (OD3) was issued. The basic Army field or combat uniform for temperate or cool climates consisted of the basic wool uniform, without tie, along with a field jacket or wool overcoat, leggings, helmet and web gear. mahogany bridesmaid dresses
The standard Army shade was a light Olive Drab (OD3) to medium olive drab (OD7). The U.S. Marine Corps used its pre-war Sage Green shade and its web gear came in the pre-war "Mustard Tan" shade.
In the European theater of operations (ETO), the basic wool uniform saw the most use and had the greatest functionality, being able to keep the soldier warm in the winter with its insulation and relatively cool and breathable in Northern European summer weather. However, the Olive Drab Cotton Field Jacket came in for considerable criticism; it was poorly insulated and the light cotton shell provided little protection from wind or rain. In addition, the OD3 coloring was deemed inappropriate for use in northern Europe, as it stood out against most backdrops, making soldiers more visible targets.
