# United States Army enlisted rank insignia of World War I

The United States Army's enlisted rank insignia that was used during World War I differs from the current system. The color scheme used for the insignia's chevron was olive drab for field use uniforms or one of several colors depending on the corps on dress uniforms. The chevron system used by enlisted men during World War I came into being on July 17, 1902, and was changed to a different system in 1919. Specification 760, which was dated May 31, 1905, contained 45 different enlisted insignia that varied designs and titles by different corps of the Army. General Order Number 169, which was enacted on August 14, 1907, created an even larger variety of enlisted rank insignia. Pay grades similar to the current system were not yet in use by the U.S. Army, and instead, the pay system reflected the job assignment of the soldier rather than their rank. By the end of World War I, the system contained 128 different insignia designs.

### Other rank insignia

In 1918 the army added insignia for privates first class serving at army of corps headquarters and with the general recruiting service.
| Private First Class General Headquarters | Private First Class General Recruiting Service |
Change number 4 to Special Regulation 42 dated May 7, 1918, prescribes insignia for the rank of motor sergeant. It, along with the insignia for chauffeurs is listed under general application for all branches. An article in the Army and Navy Register from July 4, 1918 states that the rank of motor sergeant had been created under authority granted to the president to reorganize the army as needed during the war. The article goes on the state that there was a law before congress that would create the rank of motor sergeant in all branches and expand the chauffeur ranks also to all branches. This law did not pass.
Various general orders from the American Expeditionary Force do show chauffeurs in various organizations, but as a rank, only in the Signal Corps. However the title of motor sergeant is never mentioned. Nor is it used in army order from the War Department itself. Assistant chauffeurs are listed on tables of organization as privates with duty as chauffeurs in division trains and various organizations in the Coast Artillery Corps.
| Motor Sergeant | Assistant Chauffeur |
