Benjamin Leslie Harrison (July 23, 1928 – January 22, 2022) was an officer in the United States Army who contributed to the tactics of modern airmobile warfare involving the integration of helicopters with infantry and armor forces for both rapid deployment and subsequent support.

General Harrison was an early advocate, theorist and practitioner of these tactics, commonly referred to as "air assault."

They are analogous to the revolutionary use of armor and air support with infantry in blitzkrieg warfare in early World War II, and are critical to modern military doctrine as practiced in Vietnam, Iraq and Afghanistan.
