DEC 11, 2019 - On December 9, 1942, after the start of World War II, KA-BAR submitted a knife to the United States Marine Corps in hopes that it would become a general issue to that branch of the military. The USMC KA-BAR was adopted by the Marines as well as the Army, Navy, Coast Guard and Underwater Demolition Teams. Years after World War II, many KA-BAR knives were unofficially reactivated in the Korean, Vietnam, Desert Storm, and Iraqi Freedom conflicts. U.S. Marine Corps photo by Cpl. Taryn
