Marine Defense Battalions
Marine Defense Battalions were United States Marine Corps battalions charged with coastal and air defense of advanced naval bases during World War II. They maintained large anti-ship guns, anti-aircraft guns, searchlights, and small arms to repel landing forces. Organization Unlike the mobile Marine forces involved in offensive actions, defense battalions were detached to key outposts, in the Pacific and one in Iceland, and remained at the station they defended. Most varied greatly in size and equipment. The battalions often had several coastal gun batteries, several anti-aircraft batteries, a detection battery (searchlights and radar), and machine gun units. While a few had composite infantry companies attached, most defense battalions were responsible for providing their own riflemen. A 1939 table of organization and equipment (TOE) included:Bogart, Charles H., "Fifth Marine Defense Battalion in Iceland", ''Coast Defense Journal'', Vol. 29, Issue 3, August 2015, Coast Defense ...

3-inch Gun M3
The 3-inch anti-aircraft gun M3 was an anti-aircraft gun which served throughout the 1930s and possibly into early World War II. Developed from the earlier 3-inch M1917 and 3-inch M1918 guns, it was in the process of being replaced by the time of the US entry into World War II, but was subsequently adapted into an anti-tank gun role, both free-standing (as the 3-inch M5) and in a self-propelled tank destroyer (the M10). It may have seen action in the Pacific Theatre. History During the late 1920s, M1917 and M1918 guns were fitted with removable barrel liners and re-designated as 3-inch M1, M2, or M3 guns, depending on the variant they were upgraded from. The most numerous variant was the M3 which was introduced in 1928 and consisted of a new barrel with a removable autofretted liner. During the 1930s further upgrades were proposed but these were abandoned with the adoption of the 90 mm gun M1 in 1938. Design The M3 consisted of a barrel 50 calibers in length, which ...

Imperial Japanese Navy
The Imperial Japanese Navy (IJN; Kyūjitai: Shinjitai: ' 'Navy of the Greater Japanese Empire', or ''Nippon Kaigun'', 'Japanese Navy') was the navy of the Empire of Japan from 1868 to 1945, when it was dissolved following Japan's surrender in World War II.

The Imperial Japanese Navy was the third largest navy in the world by 1920, behind the Royal Navy and the United States Navy (USN). It was supported by the Imperial Japanese Navy Air Service for aircraft and airstrike operation from the fleet. It was the primary opponent of the Western Allies in the Pacific War. The origins of the Imperial Japanese Navy go back to early interactions with nations on the Asian continent, beginning in the early medieval period and reaching a peak of activity during the 16th and 17th centuries at a time of cultural exchange with European powers during the Age of Discovery.

Landing Operation
A landing operation is a military action during which a landing force, usually utilizing landing craft, is transferred to land with the purpose of power projection ashore. With the proliferation of aircraft, a landing may refer to amphibious forces, airborne forces, or a combination of both. Landing of ships In a military invasion conducted by sea, the landing and establishment of a beachhead is a critical phase. In the ''Iliad'', the landing operation of the Achaean navy is described in book three. Since the Trojans had been warned of the invasion, the beach was defended. In Greek polytheism, the ἱερά ἐπιβατήρια were sacrifices offered to the gods after a successful landing. A λόγος ἐπιβατήριον was a dignified speech delivered upon disembarkation, contrasting with an ἀποβατήριον (''apobaterion''), the speech delivered upon departure. Air landing troops Missions of air landing troops, as defined by the U.S. FM 100–5, ''Operat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Advanced Base Force
The United States Marine Corps's Advanced Base Force (Advance Base Force in some references) was a coastal and naval base defense force that was designed to set up mobile and fixed bases in the event of major landing operations within, and beyond, the territorial United States.Commander Richard H. Jackson, USN, ''History of the Advanced Base'' (May 15, 1913) and ''The Naval Advanced Base'' (May 29, 1915); Subject File 408, Records of the General Board. * General Board to SecNav, "Letter to the Secretary of the Navy (LSSN)"; August 13, 1906. * General Board memo; May 29, 1915. Established in the beginning of the 20th century, the Advanced Base Force was the United States' first combined task force built on the concept of the Marine Corps' traditional role in expeditionary warfare. The slow development of the advanced base force played a significant role in the controversy over the removal of the ships' guards (Marines on Navy ships) in 1908–1909.Millett, Allan R., ''Semper Fideli ...
