Landing Craft Infantry
The Landing Craft Infantry (LCI) were several classes of landing craft used by the Allies to land large numbers of infantry directly onto beaches during World War II. They were developed in response to a British request for seagoing amphibious assault ships capable of carrying and landing substantially more troops than their smaller assault landing craft (LCA). The result was a small steel ship that could land 200 men, traveling from rear bases on its own bottom at a speed of up to 15 knots. Some 923 were built starting in 1943, serving in both the Pacific and European theaters, including a number that were converted into heavily armed beach assault support ships. The LCI(L) supplemented the small LCAs/ LCVPs as a way to get many troops ashore before a dock could be captured or built. As such, they were the largest dedicated beachable infantry landing craft (the larger infantry landing ship (LSI) was a transporter for men and small craft such as the British LCA) in the Allied in ...

Invasion Training In England 02
An invasion is a Offensive (military), military offensive of combatants of one geopolitics, geopolitical Legal entity, entity, usually in large numbers, entering territory (country subdivision), territory controlled by another similar entity, often involving Crime of aggression, acts of aggression. Generally, invasions have objectives of conquering, liberating or reestablishing control or authority over a territory; forcing the partition of a country; altering the established government or gaining concessions from said government; or a combination thereof. An invasion can be the cause of a war, be a part of a larger strategy to end a war, or it can constitute an entire war in itself. Due to the large scale of the operations associated with invasions, they are usually Strategy, strategic in planning and execution.

Infantry
Infantry, or infantryman are a type of soldier who specialize in ground combat, typically fighting dismounted. Historically the term was used to describe foot soldiers, i.e. those who march and fight on foot. In modern usage, the term broadly encompasses a wide variety of subspecialties, including light infantry, irregular infantry, heavy infantry, mountain infantry, motorized infantry, mechanized infantry, Airborne forces, airborne infantry, Air assault, air assault infantry, and Marines, naval infantry. Other subtypes of infantry, such as line infantry and mounted infantry, were once commonplace but fell out of favor in the 1800s with the invention of more accurate and powerful weapons. Etymology and terminology In English, use of the term ''infantry'' began about the 1570s, describing soldiers who march and fight on foot. The word derives from Middle French , from older Italian (also Spanish) ''infanteria'' (foot soldiers too inexperienced for cavalry), from Latin '' ...

Electro-Motive Division
Electro-Motive Diesel (abbreviated EMD) is a brand of diesel-electric locomotives, locomotive products and diesel engines for the rail industry. Formerly a division of General Motors, EMD has been owned by Progress Rail since 2010. Electro-Motive Diesel traces its roots to the Electro-Motive Engineering Corporation, founded in 1922 and purchased by General Motors in 1930. After purchase by GM, the company was known as GM's Electro-Motive Division. In 2005, GM sold EMD to Greenbriar Equity Group and Berkshire Partners, and in 2010, EMD was sold to Progress Rail, a subsidiary of the heavy equipment manufacturer Caterpillar. Upon the 2005 sale, the company was renamed to Electro-Motive Diesel. EMD's headquarters and engineering facilities are based in McCook, Illinois, while its final locomotive assembly line is located in Muncie, Indiana. EMD also operates a traction motor maintenance, rebuild, and overhaul facility in San Luis Potosí, Mexico. As of 2008, EMD employed approx ...

Roots Blower
The Roots blower is a positive displacement lobe pump which operates by pumping a fluid with a pair of meshing lobes resembling a set of stretched gears. Fluid is trapped in pockets surrounding the lobes and carried from the intake side to the exhaust. The Roots blower design does not incorporate any reduction in volume/increase in pressure as air or other fluid passes through, hence it can best be described as a blower rather than a supercharger unlike some other designs of "supercharger" such as cozette, centric, Shorrock supercharger, Powerplus supercharger and also the axial flow Eaton type supercharger which have internal "compression". The most common application of the Roots-type blower has been the induction device on two-stroke diesel engines, such as those produced by Detroit Diesel and Electro-Motive Diesel. Roots-type blowers are also used to supercharge four-stroke Otto cycle engines, with the blower being driven from the engine's crankshaft via a toot ...

Detroit Diesel Series 71
The Detroit Diesel Series 71 is a two-stroke diesel engine series, available in both inline and V configurations, manufactured by Detroit Diesel. The number 71 refers to the nominal displacement per cylinder in cubic inches, a rounding off of . Inline models included one, two, three, four and six cylinders, and the V-types six, eight, 12, 16, and 24 cylinders. The two largest V units used multiple cylinder heads per bank to keep the head size and weight to manageable proportions, the V-16 using four heads from the four-cylinder inline model, and the V-24 using four heads from the inline six-cylinder model. This feature also assisted in reducing the overall cost of these large engines by maintaining parts commonality with the smaller models. History The inline six-cylinder 71 series engine was introduced as the initial flagship product of the Detroit Diesel Engine Division of General Motors in 1938. This engine was in high demand during WWII, necessitating a dramatic incr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2-stroke
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes of the piston, one up and one down, in one revolution of the crankshaft in contrast to a four-stroke engine which requires four strokes of the piston in two crankshaft revolutions to complete a power cycle. During the stroke from bottom dead center to top dead center, the end of the exhaust/intake (or scavenging) is completed along with the compression of the mixture. The second stroke encompasses the combustion of the mixture, the expansion of the burnt mixture and, near bottom dead center, the beginning of the scavenging flows. Two-stroke engines often have a higher power-to-weight ratio than a four-stroke engine, since their power stroke occurs twice as often. Two-stroke engines can also have fewer moving parts, and thus be cheaper to manufacture and weigh less. In countries and regions with stringent emissions regulation, two-stroke engines ha ...

Iwo Jima
is one of the Japanese Volcano Islands, which lie south of the Bonin Islands and together with them make up the Ogasawara Subprefecture, Ogasawara Archipelago. Together with the Izu Islands, they make up Japan's Nanpō Islands. Although south of Tokyo on Honshu, Iwo Jima is administered as part of the Ogasawara Subprefecture of the Tokyo Metropolitan Government. Only in size, the island is still volcanic island, volcanic and emits sulfurous gases. The highest point of Iwo Jima is Mount Suribachi at high. Although likely passed by Micronesians who made their way to the Bonins to the north, Iwo Jima was largely ignored by the Spanish Empire, Spanish, Dutch Empire, Dutch, British Empire, British, and Empire of Japan, Japanese until a relatively late date after its 1543 rediscovery. The Japanese eventually colonized the island, administering it as the Iojima, Tokyo, Ioto or Iojima Village under Tokyo's jurisdiction until all civilians were forcibly evacuated to Honshu in July 1 ...

Battle Of Anzio
The Battle of Anzio was a battle of the Italian Campaign (World War II), Italian Campaign of World War II that commenced January 22, 1944. The battle began with the Allies of World War II, Allied amphibious landing known as Operation Shingle, and ended on June 4, 1944, with the liberation of Rome. The operation was opposed by German and by Italian Italian Social Republic, ''Repubblica Sociale Italiana'' (RSI) forces in the area of Anzio and Nettuno. Allied landings on the Italian mainland began in September 1943, and after slow gains against German resistance, the progress was stopped in December 1943 at the German defensive Gustav Line, south of Rome. The operation was initially commanded by Major General John P. Lucas, of the U.S. Army, commanding VI Corps (United States), U.S. VI Corps with the intent to outflank German forces at the Winter Line and enable an attack on Rome. The success of an amphibious landing at that location, in a basin consisting substantially of reclaim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
