On March 16th, 1943 Beach Jumper Unit ONE (BJU-1) was commissioned with the mission "To assist and support the operating forces in the conduct of Tactical Cover and Deception in Naval Warfare." Eleven BJUs deployed during the war, and were used in all theaters. The Beach Jumpers raided false landing zones and shore defenses during amphibious attacks, sowing confusion with the enemy about actual landing sites and causing the enemy to defend in the wrong place. To carry out these deceptions, their boats were equipped with two .50 caliber machine guns, 10 window rockets, smoke generators, and floating time-delay explosive packs. They were also outfitted with naval balloons and communications and psychological operations equipment, including recorders, speakers, generators, and radio jammers. The balloons included radar reflective strips that when towed would cause Beach Jumper units to appear to enemy radar operators as a larger force than they actually were.
