190318-N-MW964-1022 PORT HUENEME, Calif. (March 13, 2019) Seabees from Naval Mobile Construction Battalion (NMCB) 5 and Marines from I Marine Expeditionary Force direct the offload of a road grader from the Military Sealift Command container ship USNS SGT William R. Button (T-AK 3012) during maritime prepositioning force training in support of Pacific Blitz 2019 (PacBlitz19). The inherently dynamic, scalable, and combined-arms capability of MAGTFs joined with mobility and sustainability provided by amphibious ships gives us an asymmetric advantage over adversaries. PacBlitz19 increases the ability of all participants to plan, communicate and conduct complex amphibious operations. (U.S. Navy photo by Engineering Aid 1st Class Heather Salzman/Released)
