In March of 2022, a redesignation ceremony presided over by Commanding Officer Col. Timothy S. Brady, Jr., on Marine Corps Base Hawaii marked the transition of 3d Marines, a traditional infantry regiment, to 3d Marine Littoral Regiment - the first of its kind. Over the next year, 3d MLR would adopt three subordinate battalions - 3d Littoral Combat Team, 3d Littoral Logistics Battalion, and 3d Littoral Anti-Air Battalion. The unit’s unique construct was designed with potential adversaries in mind. 3d Littoral Combat Team - redesignated from 1st Battalion, 3d Marines - adopted Force Design's restructuring of the infantry battalion. More lightweight and maneuverable than the legacy model, 3d LCT adopted lessons learned from Infantry Battalion Experimentation 2030 and employs three rifle companies, a headquarters company, and a medium-range missile battery. 3d Littoral Logistics Battalion - redesignated from Combat Logistics Battalion 3 under 3d Marine Logistics Group - is organized and trained to provide 3d MLR with tactical logistics and explosive ordnance disposal support. The reactivation of 3d Littoral Anti-Air Battalion was a historic milestone, as the unit inherited the lineage of 3d Light Anti-Aircraft Battalion - a decorated unit with history dating back to World War II. While 3d LAAB’s mission is not new to the Marine Corps, the unit’s alignment under 3d MLR reflects the formation’s innovative way of employing air defense, air surveillance early warning, and air control to increase the commander’s overall battlespace awareness.
