Construction Battalion Detachment Detachment

Still another specialized Seabee unit was the construction battalion detachment, ranging in size from 6 to 600 men, depending on the specialized nature of its function. These detachments did everything from operating tire-repair shops to dredges. A principal use for them, however, was the handling, assembling, launching, and placing of pontoon causeways.
