In 1931, the unit was re-designated as the 11th Infantry Battalion, United States Marine Corps Reserve Organized. With the outbreak of worldwide hostilities in 1940 the battalion was mobilized and joined the 1st Battalion, 6th Marines for duty in Iceland.

IWO JIMA In 1944 when the 4th Marine Division was preparing for the assault on Iwo Jima it had a single Pioneer Battalion, the 4th, which was assigned to the 25th RCT.[1] 1/25 was to be the left assault Battalion on blue beach 1 and Baker Co. was assigned to them. 3/25 was to be the right assault Battalion on blue beach 2 and Charlie Co. was assigned to them. Dog Co. 133 Naval Construction Battalion was tasked to the 4th Pioneers as their reserve. The 133rd CB was chosen to be the shore party for the 23rd RCT on yellow beaches to fill the billet of deactivated 3rd Battalion 20th Marines. Able Co. 4th Pioneers was split and attached to A & B Companies 133rd CB on beaches yellow 1 and yellow 2.[2] 1/23 was the left assault Battalion on yellow 1 with A Co. 133, 2/23 was the right assault battalion on yellow 2. H-Hour was 0900 and the first shore parties were on the beach before 0930. For the next 18 days the Pioneers and Seabees worked together on yellow and blue beaches until they were relieved by the Army garrison shore party on D+18.[3]

The battalion remained in San Diego until 31 October 1945 when it was deactivated. On 7 August 1945 the 4th Shore Party Battalion was reactivated in Seattle, Washington, and stationed at 7500 Sand Point Way, NE aboard the Naval Support Activity. During the next 31 years the battalion saw many small detachments deploy worldwide to include service in Korea and the Republic of Vietnam. On 17 December 1978, the unit remained in place in Seattle, Washington. In 1990, the 4th Shore Party Battalion was again called for service in Operations Desert Shield/Storm, and was awarded the Meritorious Unit Commendation.

In October 1993, the battalion grew in size as the Landing Support Equipment Company at Vienna, Ohio, was re-designated and assigned to the battalion. The 4th Landing Support Battalion moved to Fort Lewis, Washington in January 1995. The Naval and Marine Corps Training Center was officially dedicated during a ceremony on 3 March 1995.

In February 2003 many of the reserve units making up 4th Landing Support Battalion were called into active duty to support the start of Operation Iraq Freedom. Many went over to Iraq to augment other Marine units as combat replacement troops, while many stayed at Camp Pendleton forming the temporary Combat Service Support Company 147 (CSSC-147). CSSC-147 worked with other Marine units and branches of the military throughout Southern California in shipping supplies over to Iraq throughout most of 2003.

On 7 September 2013, 4th Landing Support Battalion conducted its official de-activation ceremony at the Battalion headquarters on Joint Base Lewis McCord WA. That same day, Combat Logistics Battalion 23 officially uncased its colors for the first time.[4] The newest CLB in the Marine Corps, CLB-23 is organized to echo its active duty counterparts within the USMC.
