The 24th Cavalry Division was a cavalry division of the United States Army, mostly drawn from the National Guards of the Midwest states. It was created after World War I from the perceived need for additional cavalry units. It numbered in succession of the Regular Army divisions, which were not all active at its creation. Going into World War II, the US Army Cavalry Branch contained three Regular Army, four National Guard, and six Organized Reserve cavalry divisions, as well as one independent cavalry brigade.
