Adm. Moreell's concept model CB was a USMC trained military equivalent of those civilian companies: able to work anywhere, under any conditions or circumstances. It was realized that CBs were flexible, adaptable and could be utilized in every theater of operations. The use of USMC organization allowed for smooth co-ordination, integration or interface between NCF and Marine Corps elements. Additionally, CBs could be deployed individually or in multiples as the project scope and scale dictated. What distinguishes Seabees from Combat Engineers are the skill sets. Combat Engineering is but a sub-set in the Seabee toolbox. They have a storied legacy of creative field ingenuity, stretching from Normandy and Okinawa to Iraq and Afghanistan. Adm. Ernest King wrote to the Seabees on their second anniversary, ""Your ingenuity and fortitude have become a legend in the naval service."" Seabees believe that anything they are tasked with, they "Can Do". They were unique at conception and remain unchanged from Adm. Moreell's model today. In the October 1944 issue of "Flying", the Seabees are described as "a phenomenon of World War II". Since their creation, all Seabee advanced military training has been under USMC instruction. Even so, they always bring their toolbox. One of those tools is the ingenuity Admiral King referenced. They gained fame for their application of it during World War II. The UDTs and flamethrowing tanks are declassified top secret examples. Postwar they followed with more of the same for the CIA and State Department. Together with their USMC training and ability to appropriate anything, they provide the Navy an unconventional asset found nowhere else in the U.S military.
