D Co. 133 Naval Construction Battalion was posted TAD to the 4th Pioneers as their reserve. The 133rd Seabees were chosen to be the Shore Party for the 23rd RCT on yellow beaches to fill in for the Pioneer Battalion the 4th was short. A Co 4th Pioneers was split in two with A Co. 133 Naval Construction Battalion attached to them on beach yellow 1. The other half had B Co. 133 NCB attached and were on beach yellow 2.[2] 1/23 was the left assault Battalion on yellow 1 and the half with A Co. 133 was assigned there. 2/23 was to be the right assault Battalion on yellow 2 and the half with B Co 133 was posted there.

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.

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).
