The 2nd Combat Engineer Battalion was activated on 1 November 1940 in order to support the 2nd Marine Brigade.

On 1 April 1941, the battalion was assigned to Division Special Troops of the 2nd Marine Division.

Upon Arrival, Headquarters and Service Company and Company A were assigned to Construct Camp Caitlin, Oahu.

On 8 September 1942 2nd Engineer Battalion was redesignated as "1st Battalion, 18th Marines". During World War II, the engineers of 18th Marines participated in Campaigns on Guadalcanal, Tarawa, Saipan, Tinian, and Okinawa. 18th Marines was redesignated 16 August 1944 as the 2nd Engineer Battalion.

Engineers with Battalion Landing Team's 1/8, 3/6, and 2/2 landed in Lebanon during the summer of 1958. The 2nd Pioneer Battalion maintained a combat-ready posture during the October/November Cuban Missile Crisis while on maneuvers in the Caribbean.
