Seabees
United States Naval Construction Battalions, better known as the Navy Seabees, form the U.S. Naval Construction Force (NCF). The Seabee nickname is a heterograph of the initial letters "CB" from the words "Construction Battalion". Depending upon context, "Seabee" can refer to all enlisted personnel in the USN's occupational field 7 (OF-7), all personnel in the Naval Construction Force (NCF), or Construction Battalion. Seabees serve both in and outside the NCF. During World War II they were plankowner, plank-holders of both the Naval Combat Demolition Units and the Underwater Demolition Teams (UDTs). The men in the NCF considered these units to be "Seabee". In addition, Seabees served as elements of Cubs, Lions, Acorns and the United States Marine Corps. They also provided the manpower for the top secret CWS Chemical Warfare Service: Flame Tank Group Seabees, Flame Tank Group. Today the Seabees have many special task assignments starting with Camp David and the Naval Support Unit at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Combat Demolition Units
Underwater Demolition Teams (UDT), or frogmen, were amphibious units created by the United States Navy during World War II with specialized non-tactical missions. They were predecessors of the navy's current SEAL teams. Their primary WWII function began with reconnaissance and underwater demolition of natural or man-made obstacles obstructing amphibious landings. Postwar they transitioned to scuba gear changing their capabilities. With that they came to be considered more elite and tactical during the Korean and Vietnam Wars. UDTs were pioneers in underwater demolition, closed-circuit diving, combat swimming, and midget submarine (dry and wet submersible) operations. They later were tasked with ensuring recovery of space capsules and astronauts after splash down in the Mercury, Gemini and Apollo space flight programs. Commando training was added making them the forerunner to the United States Navy SEAL program that exists today. In 1983, after additional SEAL training, the ...

Battle Of Iwo Jima
The Battle of Iwo Jima (19 February – 26 March 1945) was a major battle in which the United States Marine Corps (USMC) and United States Navy (USN) landed on and eventually captured the island of Iwo Jima from the Imperial Japanese Army (IJA) during World War II. The American invasion, designated Operation Detachment, had the purpose of capturing the island with its two airfields: South Field and Central Field. The Japanese Army positions on the island were heavily fortified, with a dense network of bunkers, hidden artillery positions, and of tunnels. The American ground forces were supported by extensive naval artillery and had complete air supremacy provided by U.S. Navy and Marine Corps aviators throughout the battle. The five-week battle saw some of the fiercest and bloodiest fighting of the Pacific War. The Japanese combat deaths numbered three times the number of American deaths, but uniquely among Pacific War Marine battles, the American total casualties (dead an ...

Battle Of Los Negros
The Admiralty Islands campaign (Operation Brewer) was a series of battles in the New Guinea campaign of World War II in which the United States Army's 1st Cavalry Division took the Japanese-held Admiralty Islands. Acting on reports from airmen that there were no signs of enemy activity and the islands might have been evacuated, General Douglas MacArthur accelerated his timetable for capturing the Admiralties and ordered an immediate reconnaissance in force. The campaign began on 29 February 1944 when a force landed on Los Negros, the third-largest island in the group. By using a small, isolated beach where the Japanese had not anticipated an assault, the force achieved tactical surprise, but the islands proved to be far from unoccupied. A furious battle over the islands ensued. In the end, air superiority and command of the sea allowed the Allies to heavily reinforce their position on Los Negros. The 1st Cavalry Division could then overrun the islands. The campaign officia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Peleliu
The Battle of Peleliu, codenamed Operation Stalemate II by the US military, was fought between the United States and Japan during the Mariana and Palau Islands campaign of World War II, from September 15 to November 27, 1944, on the island of Peleliu. US Marines of the 1st Marine Division and then soldiers of the US Army's 81st Infantry Division, fought to capture an airfield on the small coral island of Peleliu. The battle was part of a larger offensive campaign known as Operation Forager, which ran from June to November 1944 in the Pacific Theater. Major General William Rupertus, the commander of the 1st Marine Division, predicted that the island would be secured within four days. However, after repeated Imperial Japanese Army defeats in previous island campaigns, Japan had developed new island-defense tactics and well-crafted fortifications, which allowed stiff resistance and extended the battle to more than two months. The heavily-outnumbered Japanese defenders put up su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Tinian
The Battle of Tinian was a battle of the Pacific campaign of World War II, fought on the island of Tinian in the Mariana Islands from 24 July until 1 August 1944. The 8,000-man Japanese garrison was eliminated, and the island joined Saipan and Guam as a base for the Twentieth Air Force. Background A two-prong attack through the Central Pacific and the Philippines was adopted at the 1943 Cairo Conference. Operation Granite II, was a U.S. Navy devised strategy of island hopping, calling for the seizure of Saipan, Tinian and Guam. The Gilbert and Marshall Islands had been seized by the summer of 1944, while some Japanese garrisons were left to starve. Following the conclusion of the Battle of Saipan on 9 July, the US began preparations for attacking nearby Tinian. Tinian was part of Japan's South Seas Mandate. By June 1944, it had a population of 15,700 Japanese civilians, including 2,700 ethnic Koreans and 22 ethnic Chamorro. The Japanese defending the island, the 50th I ...

Battle Of Guadalcanal
The Guadalcanal campaign, also known as the Battle of Guadalcanal and codenamed Operation Watchtower by American forces, was a military campaign fought between 7 August 1942 and 9 February 1943 on and around the island of Guadalcanal in the Pacific theater of World War II. It was the first major land offensive by Allied forces against the Empire of Japan. On 7 August 1942, Allied forces, predominantly United States Marines, landed on Guadalcanal, Tulagi, and Florida in the southern Solomon Islands, with the objective of using Guadalcanal and Tulagi as bases in supporting a campaign to eventually capture or neutralize the major Japanese base at Rabaul on New Britain. The Japanese defenders, who had occupied those islands since May 1942, were outnumbered and overwhelmed by the Allies, who captured Tulagi and Florida, as well as the airfield – later named Henderson Field – that was under construction on Guadalcanal. Surprised by the Allied offensive, the Japanese made se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Bougainville
The Bougainville campaign was a series of land and naval battles of the Pacific campaign of World War II between Allied forces and the Empire of Japan, named after the island of Bougainville. It was part of Operation Cartwheel, the Allied grand strategy in the South Pacific. The campaign took place in the Northern Solomons in two phases. The first phase, in which American troops landed and held the perimeter around the beachhead at Torokina, lasted from November 1943 through November 1944. The second phase, in which primarily Australian troops went on the offensive, mopping up pockets of starving, isolated but still-determined Japanese, lasted from November 1944 until August 1945, when the last Japanese soldiers on the island surrendered. Operations during the final phase of the campaign saw the Australian forces advance north towards the Bonis Peninsula and south towards the main Japanese stronghold around Buin, although the war ended before these two enclaves were compl ...

Battle Of Guam (1944)
The Battle of Guam (21 July–10 August 1944) was the American recapture of the Japanese-held island of Guam, a U.S. territory in the Mariana Islands captured by the Japanese from the United States in the First Battle of Guam in 1941 during the Pacific campaign of World War II. The battle was a critical component of Operation Forager. The recapture of Guam and the broader Mariana and Palau Islands campaign resulted in the destruction of much of Japan's naval air power and allowed the United States to establish large airbases from which it could bomb the Japanese home islands with its new strategic bomber, the Boeing B-29 Superfortress. Background Guam, at 212 square miles (543 square kilometers), is the largest island of the Marianas, with a length of 32 miles (52 km) and a width ranging from 12 miles (19.31 km) to four miles (6.44 km) at different points of the island. It had been a United States possession since its capture from Spain in 189 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Tarawa
The Battle of Tarawa was fought on 20–23 November 1943 between the United States and Japan at the Tarawa Atoll in the Gilbert Islands, and was part of Operation Galvanic, the U.S. invasion of the Gilberts. Nearly 6,400 Japanese, Koreans, and Americans died in the fighting, mostly on and around the small island of Betio, in the extreme southwest of Tarawa Atoll. The Battle of Tarawa was the first American offensive in the critical central Pacific region. It was also the first time in the Pacific War that the United States had faced serious Japanese opposition to an amphibious landing. Previous landings met little or no initial resistance, but on Tarawa the 4,500 Japanese defenders were well-supplied and well-prepared, and they fought almost to the last man, exacting a heavy toll on the United States Marine Corps. The losses on Tarawa were incurred within 76 hours. Background American strategic decisions To set up forward air bases capable of supporting operations across ...

Battle Of Saipan
The Battle of Saipan was a battle of the Pacific campaign of World War II, fought on the island of Saipan in the Mariana Islands from 15 June to 9 July 1944 as part of Operation Forager. It has been referred to as the "Pacific D-Day" with the invasion fleet departing Pearl Harbor on 5 June 1944, the day before Operation Overlord in Europe was launched, and launching nine days after. The U.S. 2nd Marine Division, 4th Marine Division, and the Army's 27th Infantry Division, commanded by Lieutenant General Holland Smith, defeated the 43rd Infantry Division of the Imperial Japanese Army, commanded by Lieutenant General Yoshitsugu Saitō. The loss of Saipan, with the deaths of at least 29,000 troops and heavy civilian casualties, precipitated the resignation of Prime Minister of Japan Hideki Tōjō and left the Japanese archipelago within the range of United States Army Air Forces B-29 bombers. Background In the campaigns of 1943 and the first half of 1944, the Allies had capt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Military Engineering
Military engineering is loosely defined as the art, science, and practice of designing and building military works and maintaining lines of military transport and military communications. Military engineers are also responsible for logistics behind military tactics. Modern military engineering differs from civil engineering. In the 20th and 21st centuries, military engineering also includes other engineering disciplines such as mechanical and electrical engineering techniques. According to NATO, "military engineering is that engineer activity undertaken, regardless of component or service, to shape the physical operating environment. Military engineering incorporates support to maneuver and to the force as a whole, including military engineering functions such as engineer support to force protection, counter-improvised explosive devices, environmental protection, engineer intelligence and military search. Military engineering does not encompass the activities undertaken by those ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
