The ”’Special Engineer Detachment”’ (SED) was a [[US Army]] program that identified enlisted personnel with technical skills, such as machining, or who had some science education beyond high school. Those identified were organized into the Special Engineer Detachment, or SED. SED personnel began arriving at [[Los Alamos National Laboratory|Los Alamos]] in October 1943.
