and map the existing road network. That survey was extensively used during the Vietnam War. see Notes Malaria and Epidemic Control Group BUMED created the Malaria and Epidemic Control Group to deal with insect-borne diseases. Between August 1942, and February 1943, American troops in the Pacific averaged 10 malaria cases for every combat injury. Seabees oiled, drained and sprayed mosquito breeding areas and inspected and fumigated ships and aircraft transiting malaria-infested areas. It was an important task that absolutely needed to be done in order for the United States to field an effective combat force. On Guadalcanal the 63rd CB had malaria control as its primary task. At Gulfport a school was established to train Battalions for the Malaria and Epidemic Control Group. World War II Seabees outside the NCF During World War II Seabees were tasked outside the NCF in the USMC, NCDUs, and UDTs. Marine Corps USMC historian Gordon L. Rottman wrote "that one of the biggest contributions the Navy made to the Marine Corps during WWII was the creation of the Seabees". In exchange, the Corps would be influential upon the CB organization and its history. After the experience of Guadalcanal the Department of War decided that the Marines and Seabees would make all subsequent landings together. That arrangement led to numerous Seabee claims that they had landed first, even leaving signs on the beach asking the Marines "What took you so long?" The Seabees in the UDTs made an effort of this that their mates in the CBs approved of. When the first three CBs were formed the Seabees did not have a base of their own. Upon leaving boot the recruits were sent to National Youth Administration camps in Illinois, New Jersey, New York, and Virginia to receive military training from the Marine Corps. The Marine Corps listed CBs on their Table of organization: "D-Series Division" for 1942, "E-Series Division" for 1943, and "Amphibious Corps" for 1944–45. When CBs were created the Marine Corps wanted one for each of the three Marine Divisions, but were told no because of war priorities. Even so, early Seabee units were connected with Marine Corps ops. The 1st Naval Construction Detachment (Bobcats) together with and A Co CB 3 was transferred to the Marines and redesignated 3rd Battalion 22nd Marines. The Bobcats had deployed without receiving advanced military training. The 22nd Marines took care of that. The 4th Construction
