The US armed forces were responsible for many tactical innovations during the years 1941–45, but in no field was US mastery more complete than amphibious warfare. In the vast, almost empty battlefield of the Pacific the US Navy and Marine Corps were obliged to develop every aspect of the amphibious assault landing in painstaking detail, from the design of many new types of vessel, down to the tactics of the rifle platoon hitting the beach, and the logistic system without which they could not have fought their way inland. This fascinating study offers a clear, succinct explanation of every phase of these operations as they evolved during the war years, illustrated with detailed color plates and photographs.

Sea mines have been important in naval warfare throughout history and continue to be so today. They have caused major damage to naval forces, slowed or stopped naval actions and commercial shipping, and forced the alteration of strategic and tactical plans. The threat posed by sea mines continues, and is increasing, in today's world of inexpensive advanced electronics, nanotechnology, and multiple potential enemies, some of which are difficult to identify. This report assesses the Department of the Navy's capabilities for conducting naval mining and countermining sea operations.

Contains the definitive history of the extensive but little known U.S. Army amphibious operations during the Korean War, 1950-1953. Provides insights to modern planners crafting future joint or combined operations in that part of the world.Originally published in 2008. Illustrated.

FROM our entry into the war at Pearl Harbor in December 1941 until the Japanese surrender in September 1945, every major offensive campaign launched by the United States was initiated by an amphibious assault. Our landings at North Africa in November 1942, at Sicily and Italy in July and September 1943, and at Normandy and Southern France in June and September 1944 ended in the defeat of the German armies in Western Europe by the Allied Expeditionary Force in May 1945. The Pacific offensive, which began in the South Pacific with the landings at the Solomons in August 1942 and in the Central Pacific at the Gilberts in November 1943, carried us 3,000 miles to the Philippine Islands and 5,000 miles through to the inner defenses of the empire in the Volcano and Ryukyu Islands....Amphibious warfare was the primary offensive tactic in our conduct of global war. The tactics and techniques of our landing operations represent a new and significant development in the art of war. Although military history contains many instances of landing operations conducted by both military and navy forces in all parts of the world, from the early time man first crossed the sea to wage war, the landings were generally either limited in scope and purpose or unopposed. The feasibility of amphibious raids, in which assault forces landed from the sea are withdrawn after limited operations, and of unopposed landings, relying on surprise and conducted for the purpose of subsequent military operations ashore, has long been recognized. Until the recent war, however, the effect of modern defensive weapons was considered too decisive to permit successful assault from the sea. The development of radar, aviation, coast defense guns, torpedoes, submarines, mines, defensive obstructions and obstacles, automatic weapons, highly mobile reserves, and the necessary communication facilities to coordinate and control them seemed to present insurmountable difficulties to amphibious attack.

This publication is about winning in combat. Winning requires many things: excellence in techniques, an appreciation of the enemy, exemplary leadership, battlefield judgment, and focused combat power. Yet these factors by themselves do not ensure success in battle. Many armies, both winners and losers, have possessed many or all of these attributes. When we examine closely the differences between victor and vanquished, we draw one conclusion. Success went to the armies whose leaders, senior and junior, could best focus their efforts-their skills and their resources-toward a decisive end. Their success arose not merely from excellence in techniques, procedures, and material but from their leaders' abilities to uniquely and effectively combine them. Winning in combat depends upon tactical leaders who can think creatively and act decisively.

This is the second volume in a series of chronological histories prepared by the Marine Corps History and Museums Division to cover the entire span of Marine Corps involvement in the Vietnam War. This volume details the Marine activities during 1965, the year the war escalated and major American combat units were committed to the conflict. The narrative traces the landing of the nearly 5,000-man 9th Marine Expeditionary Brigade and its transformation into the ΙII Marine Amphibious Force, which by the end of the year contained over 38,000 Marines. During this period, the Marines established three enclaves in South Vietnam’s northernmost corps area, I Corps, and their mission expanded from defense of the Da Nang Airbase to a balanced strategy involving base defense, offensive operations, and pacification. This volume continues to treat the activities of Marine advisors to the South Vietnamese armed forces but in less detail than its predecessor volume, U.S. Marines in Vietnam, 1954-1964; The Advisory and Combat Assistance Era.
