EARLY TWENTIETH CENTURY
The duties of the Noncommissioned Officer were further defined during the early 20th Century. The five or six pages of instructions that von Steuben's Regulations had provided in 1778 grew to 417 pages when the Noncommissioned Officers Manual was written in 1909, reflecting the greater complexity and bureaucratization of a modern army.
In 1902, the chevron was turned to what we would today call point up. It also was greatly reduced in size. Though many stories exist as to why the chevron's direction was changed, the most realistic is that it looked better. Clothing had become more form-fitting; indeed, the ten-inch chevron of the 1880s would have wrapped completely around the sleeve of a 1902 uniform.
