Depending on the country, service, or historical context, warrant officers are sometimes classified as the most junior of the commissioned officer ranks, the most senior of the non-commissioned officer (NCO) ranks, or in a separate category of their own. Warrant officer ranks are especially prominent in the militaries of Commonwealth nations and the United States.
Sergeant (Sgt) is a rank in use by the armed forces of many countries. It is also a police rank in some police services.

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.
