The 1st Raider Regiment enforced a common organization among the battalions. Each had a weapons company, and four rifle companies composed of three rifle platoons and a weapons platoon. The result reflected a mixture of Edson's and Carlson's ideas. Carlson's 3-man fire team and 10-man squad organizations were adopted, first by the Raiders and then by the entire Marine Corps. Edson contributed the concept of a highly trained, lightly equipped force using conventional tactics to accomplish special missions or to fill in for a line battalion.
