The debate over the creation of these elite units came to a climax when the new commander of the Pacific Fleet, Admiral Chester Nimitz, requested "commando units" for raids against lightly defended Japanese-held islands. The commandant selected the term "Raiders" and created two battalions. The 1st Raider Battalion was activated on 16 February 1942, followed by the 2nd Raider Battalion on February 19. Carlson was given a promotion to Lieutenant Colonel and placed in command of the 2nd Raiders, and Lt. Col. (later, Major General) Merritt A. "Red Mike" Edson, command of the 1st.
