CB 3 sent a detachment to Bora Bora to augment the Bobcats. In the fall of 1943 the Seabees all received orders to Noumea to join CB 3. Before that happened they were redesignated 3rd Battalion 23rd Marines. The remainder of A Co. CB 3 was transferred to the 22nd as well. Neither the Bobcats nor A Co had not received advanced military training before deploying so the 22nd Marines gave them all an intense field version on Bora Bora. Afterwards the regiment returned to Hawaii for amphibious warfare training. For the Marshalls landings 3rd Battalion was tasked as shore party, engineers and demolitions men. They would see extensive combat at the Battle of Eniwetok. When those operations were over the 22nd Marines were given a Naval Unit Commendation and the Bobcats and A Co 3 CB were released by the Marines.
