Hull-down
In sailing and warfare, to be hull down means that the upper part of a vessel or vehicle is visible, but the main, lower body (Hull (watercraft), hull) is not; the term hull up means that all of the body is visible. The terms originated with sailing and naval warfare in which the curvature of the Earth causes an approaching vessel to be first visible "sails up". Beginning in the 20th century, ''hull down'' has also been used in armoured warfare. In modern armoured warfare, hull down is a position taken up by an armoured fighting vehicle (AFV) so that its hull (the main part of the vehicle) is behind a crest or other raised ground, but its turret (or a superstructure or roof-mounted weapon) is exposed. Turret down is the position in which the vehicle's crew can observe forward from roof hatches, but the vehicle is completely hidden (usually a few metres further back from a hull-down position). The belly armour should not be exposed, because it is vulnerable to even modest antitank ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tank
A tank is an armoured fighting vehicle intended as a primary offensive weapon in front-line ground combat. Tank designs are a balance of heavy firepower, strong armour, and battlefield mobility provided by tracks and a powerful engine; their main armament is often mounted within a turret. They are a mainstay of modern 20th and 21st century ground forces and a key part of combined arms combat. Modern tanks are versatile mobile land weapons platforms whose main armament is a large- calibre tank gun mounted in a rotating gun turret, supplemented by machine guns or other ranged weapons such as anti-tank guided missiles or rocket launchers. They have heavy vehicle armour which provides protection for the crew, the vehicle's munition storage, fuel tank and propulsion systems. The use of tracks rather than wheels provides improved operational mobility which allows the tank to overcome rugged terrain and adverse conditions such as mud and ice/snow better than wheele ...

Reconnaissance
In military operations, military reconnaissance () or scouting is the exploration of an area by military forces to obtain information about enemy forces, the terrain, and civil activities in the area of operations. In military jargon, reconnaissance is abbreviated to ''recce'' (in British, Canadian, Australian English) and to ''recon'' (in American English), both derived from the root word ''reconnoitre'' / ''reconnoitering''. The types of reconnaissance include patrolling the local area of operations and long-range reconnaissance patrols, which are tasks usually realized in the United States of America by U.S. Army Rangers, cavalry scouts, and military intelligence specialists, using navy ships and submarines, Aerial reconnaissance, reconnaissance aircraft, satellites to collect raw intelligence; and establishing observation posts. Moreover, espionage is different from reconnaissance, because spies work as civilians in enemy territory. Etymology The word is derived from the ...

Wingman
A wingman (or wingmate) is the pilot of a secondary aircraft providing support or protection to a primary aircraft in a potentially dangerous situation, traditionally flying in formation to the side and slightly behind the primary craft. The term is sometimes used in reference to the secondary aircraft itself, particularly when it is an unmanned aerial vehicle (UAV) rather than human-piloted plane. According to the U.S. Air Force, Description The wingman's role is to support aerial combat by making a flight both safer and more capable: amplifying situational awareness, increasing firepower, and allowing more dynamic tactics. Origins The concept of a wingman is nearly as old as fighter aviation. On 9 August 1915, Oswald Boelcke was already acting in the role when he shot down a French airplane pursuing Max Immelmann. Colonel Robert Smith provided an extensive description of the work and role of wingmen during the Korean War. Among a wingman's primary responsibilities are ...

Overwatch (military Tactic)
Overwatch is a force protection tactic in modern warfare where one small military unit, military vehicle, vehicle, or military aircraft, aircraft supports another friendly unit while the latter executes fire and movement tactics. The term was neologism, coined in U.S. military doctrine in the 1950s. An ''overwatching'' unit typically takes a vantage position (usually a high ground or tall structure with good defilade) where it can observe the terrain far ahead, especially likely enemy positions and movements. This allows it to act as a warning system against hostile aggression and provide effective covering fire for advancing friendly units.

Platoon
A platoon is a Military organization, military unit typically composed of two to four squads, Section (military unit), sections, or patrols. Platoon organization varies depending on the country and the Military branch, branch, but a platoon can be composed of 20–50 troops, although specific platoons may range from 10 to 100 people. A platoon is typically the smallest military unit led by a Officer (armed forces), commissioned officer. The platoon leader is usually a junior officer—a Second lieutenant, second or first lieutenant or an equivalent rank. The officer is usually assisted by a platoon sergeant. Rifle platoons normally consist of a small platoon headquarters and three or four sections (Commonwealth) or squads (United States). In some armies, platoon is used throughout the branches of the army. In a few armies, such as the French Army, a platoon is specifically a cavalry unit, and the infantry use "section" as the equivalent unit. A unit consisting of several platoon ...

Company (military Unit)
A company is a Military organization#Commands, formations, and units, military unit, typically consisting of 100–250 soldiers and usually commanded by a Major (rank), major or a Captain (armed forces), captain. Most companies are made up of three to seven platoons, although the exact number may vary by country, unit type, and structure. Usually several companies are grouped as a battalion or regiment, the latter of which is sometimes formed by several battalions. Occasionally, ''independent'' or ''separate'' companies are organized for special purposes, such as the Air Naval Gunfire Liaison Company, 1st Air Naval Gunfire Liaison Company or the 3rd Force Reconnaissance Company. These companies are not organic to a battalion or regiment, but rather report directly to a higher level organization such as a Marine Expeditionary Force headquarters (i.e., a corps-level command).

Telescopic Sight
A telescopic sight, commonly called a scope informally, is an optical sighting device based on a refracting telescope. It is equipped with some form of a referencing pattern – known as a ''reticle'' – mounted in a focally appropriate position in its optical system to provide an accurate point of aim. Telescopic sights are used with all types of systems that require magnification in addition to reliable visual aiming, as opposed to non-magnifying iron sights, reflector (reflex) sights, holographic sights or laser sights, and are most commonly found on long-barrel firearms, particularly rifles, usually via a scope mount. Similar devices are also found on other platforms such as artillery, tanks and even aircraft. The optical components may be combined with optoelectronics to add night vision or smart device features. History The first experiments directed to give shooters optical aiming aids go back to the early 17th century. For centuries, different optical ...

Antitank
Anti-tank warfare refers to the military strategies, tactics, and weapon systems designed to counter and destroy enemy armored vehicles, particularly tanks. It originated during World War I following the first deployment of tanks in 1916, and has since become a fundamental component of land warfare doctrine. Over time, anti-tank warfare has evolved to include a wide range of systems, from handheld infantry weapons and anti-tank guns to guided missiles and air-delivered munitions. Anti-tank warfare evolved rapidly during World War II, leading to infantry-portable weapons. Through the Cold War of 1947–1991, the United States, anti-tank weapons have also been upgraded in number and performance. Since the end of the Cold War in 1992, new threats to tanks and other armored vehicles have included remotely detonated improvised explosive devices (IEDs). During the Russian invasion of Ukraine, Unmanned aerial vehicle, drones and loitering munitions have attacked and destroyed ...

Glacis
A glacis (, ) in military engineering is an artificial slope as part of a medieval castle or in early modern fortresses. They may be constructed of earth as a temporary structure or of stone in more permanent structure. More generally, a glacis is any slope, natural or artificial, which fulfils the above requirements. The etymology of this French word suggests a slope made dangerous with ice, hence the relationship with ''glacier''. A ''glacis plate'' is the sloped front-most section of the hull of a tank or other armoured fighting vehicle. Ancient fortifications A glacis could also appear in ancient fortresses, such as the one the ancient Egyptians built at Semna in Nubia. Here it was used by them to prevent enemy siege engines from weakening defensive walls. Hillforts in Britain started to incorporate glacis around 350 BC. Those at Maiden Castle, Dorset were high. Medieval fortifications Glacises, also called taluses, were incorporated into medieval fortifications ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bundesarchiv Bild 101I-478-2165-09A, Italien, Panzer V (Panther) Im Gelände
The German Federal Archives or Bundesarchiv (BArch) (, lit. "Federal Archive") are the national archives of Germany. They were established at the current location in Koblenz in 1952. They are subordinated to the Federal Commissioner for Culture and the Media ( Claudia Roth since 2021) under the German Chancellery, and before 1998, to the Federal Ministry of the Interior. On 6 December 2008, the Archives donated 100,000 photos to the public, by making them accessible via Wikimedia Commons. History The federal archive for institutions and authorities in Germany, the first precursor to the present-day Federal Archives, was established in Potsdam, Brandenburg in 1919, a later date than in other European countries. This national archive documented German government dating from the founding of the North German Confederation in 1867. It also included material from the older German Confederation and the Imperial Chamber Court. The oldest documents in this collection dated back to the ...
