A military cadence is a traditional call-and-response work song sung by military personnel while running or marching. Many cadences have a call and response structure of which the commanding officer, such as a sergeant, initiates a line, and the remaining soldiers, his subordinates, complete it, thus instilling teamwork and camaraderie for completion. The cadences move to the beat and rhythm of the normal speed march or running-in-formation march. This serves the purpose of keeping soldiers moving in step as a unit and in formation, while maintaining the correct beat or cadence.
