LSE 2021 allowed Marines to refine concepts such as expeditionary advanced base operations and littoral operations in a contested environment in order to provide sea control or contribute to sea denial near key maritime terrain. - An artillery Marine from 1st Battalion, 12th Marines maneuvers a Navy Marine Expeditionary Ship Interdiction System launcher across the beach aboard Pacific Missile Range Facility Barking Sands, Hawaii, Aug. 16, 2021.
