Armored Bulldozer
The armoured bulldozer is a basic tool of combat engineering. These combat engineering vehicles combine the earth moving capabilities of the bulldozer with armour which protects the vehicle and its operator in or near combat. Most are civilian bulldozers modified by addition of vehicle armour/military equipment, but some are tanks stripped of armament and fitted with a dozer blade. Some tanks (called tankdozers) have bulldozer blades while retaining their armament, but this does not make them armoured bulldozers as such, because combat remains the primary role—earth moving is a secondary task. World War II The first armoured bulldozer (D7A) was developed by the British during World War II. This was a conventional Caterpillar D7 bulldozer fitted with armour to protect the driver and the engine. The work was carried out by Jack Olding & Company Ltd of Hatfield. The bulldozer was one of several specialist armored vehicles that were collectively referred to as "Hobart's Funnie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Israel Defense Forces
The Israel Defense Forces (IDF; , ), alternatively referred to by the Hebrew-language acronym (), is the national military of the State of Israel. It consists of three service branches: the Israeli Ground Forces, the Israeli Air Force, and the Israeli Navy. It is the sole military wing of the Israeli security forces, Israeli security apparatus. The IDF is headed by the Chief of the General Staff (Israel), chief of the general staff, who is subordinate to the Ministry of Defense (Israel), defense minister. On the orders of first prime minister David Ben-Gurion, the IDF was formed on 26 May 1948 and began to operate as a Conscription in Israel, conscript military, drawing its initial recruits from the already-existing paramilitaries of the Yishuv—namely Haganah, the Irgun, and Lehi (militant group), Lehi. It was formed shortly after the Israeli Declaration of Independence and has participated in List of wars involving Israel, every armed conflict involving Israel. In the wak ...

Israeli Engineering Corps
The Israeli Combat Engineering Corps (, ''Heil HaHandasa HaKravit'') is part of the Israel Defense Forces with responsibility for mobility assurance, road breaching, defense and fortifications, counter-mobility of enemy forces, construction and destruction under fire, sabotage, explosives, bomb disposal, counter-weapons of mass destruction (NBC) and special engineering missions. The Combat Engineering Corps beret's color is silver and its symbol features a sword on a defensive tower with an explosion halo on the background. The Combat Engineering Corps mottos are ''"Always First" (ראשונים תמיד Rishonim Tamid)'' and the unofficial ''"The hard, we shall do today; the impossible, we shall do tomorrow"''. In addition to Combat Engineering Corps sappers, each infantry brigade has an engineering company trained with basic engineering and explosive ordnance disposal (EOD) skills (called פלח"הן). Combat Engineering Corps sappers and heavy equipment operators are often a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engineering Vehicle
Heavy equipment, heavy machinery, earthmovers, construction vehicles, or construction equipment, refers to heavy-duty vehicles specially designed to execute construction tasks, most frequently involving earthwork operations or other large construction tasks. ''Heavy equipment'' usually comprises five equipment systems: the implement, traction, structure, power train, and control/information. Heavy equipment has been used since at least the 1st century BC, when the ancient Roman engineer Vitruvius described a crane powered by human or animal labor in '' De architectura''. Heavy equipment functions through the mechanical advantage of a simple machine that multiplies the ratio between input force applied and force exerted, easing and speeding tasks which often could otherwise take hundreds of people and many weeks' labor. Some such equipment uses hydraulic drives as a primary source of motion. The word plant, in this context, has come to mean any type of industrial eq ...

Drawbar Pull
In automotive engineering, drawbar pull is the amount of horizontal force available to a vehicle at the drawbar for accelerating or pulling a load. Drawbar pull is a function of velocity, and in general decreases as the speed of the vehicle increases (due both to increasing resistance and decreasing transmission gear ratios). Drawbar pull is the difference between tractive effort available and tractive effort required to overcome resistance at a specified speed. Drawbar pull data for a vehicle is usually determined by measuring the amount of available tractive force using a dynamometer A dynamometer or "dyno" is a device for simultaneously measuring the torque and rotational speed ( RPM) of an engine, motor or other rotating prime mover so that its instantaneous power may be calculated, and usually displayed by the dyna ..., and then combining that data with coastdownSAE J1263, Road Load measurement and Dynamometer Simulation Using Coastdown Techniques, dated January 2 ...

Israeli Military Industries
IMI Systems, previously Israel Military Industries, also referred to as Ta'as (), was an Israeli weapons manufacturer. The company manufactured weapons, munitions and military technology mainly for the Israeli security forces (especially Israel's army, the Israel Defense Forces or IDF). On 25 November 2018, Elbit Systems completed the acquisition of IMI Systems and renamed it to Elbit Systems Land. Small arms Israel Weapon Industries' small arms offerings are notable, with numerous well identified product names and de facto 'brands'. Examples are the Uzi submachine gun and the IMI Galil assault rifle, and the Negev light machine gun. In addition, such offerings as the Jericho 941 semi-automatic pistol and Tavor assault rifle are globally recognized and marketed firearms. In the 1980s, an American firearms designer, Magnum Research, contracted IMI to re-design and manufacture a magnum caliber ( .44 Magnum, .357 Magnum and .50 AE), resulting in the production of a semi- ...
