Armored car (military) in the context of "Rocket-propelled grenade"

An armoured fighting vehicle (British English) or armored fighting vehicle (American English) (AFV) is an armed combat vehicle protected by armour, generally combining operational mobility with offensive and defensive capabilities. AFVs can be wheeled or tracked. Examples of AFVs are tanks, armoured cars, assault guns, self-propelled artilleries, infantry fighting vehicles (IFV), and armoured personnel carriers (APC).

Armoured fighting vehicles are classified according to their characteristics and intended role on the battlefield. The classifications are not absolute; two countries may classify the same vehicle differently, and the criteria change over time. For example, relatively lightly armed armoured personnel carriers were largely superseded by infantry fighting vehicles with much heavier armament in a similar role.

A ground combat vehicle, also known as a land assault vehicle or simply a combat vehicle or an assault vehicle, is a land-based military vehicle intended to be used for combat operations. They differ from non-combat military vehicles such as trucks in that they are designed for use in active combat zones, to be used in mechanized warfare and mobile infantry roles.

The classification of "combat vehicle" is a very broad category, and may include armored cars, armored personnel carriers, infantry fighting vehicles, infantry mobility vehicles, MRAPs, and tanks. Improvised fighting vehicles such as technicals can also count as combat vehicles. Most modern combat vehicles have vehicle armor, offensive or defensive weaponry, and sufficient space to carry passengers, equipment, or materiel; if the first two both apply, the vehicle may be considered an armored fighting vehicle.

An official state car is an automobile used by a government to transport its head of state or head of government in an official capacity, which may also be used occasionally to transport other members of the government or visiting dignitaries from other countries. A few countries bring their own official state car for state visits to other countries, for instance, the United States, Russia, the United Kingdom, South Korea, Germany and Japan. It also may serve as an automotive symbol of the head of state and their country. An official state car must have adequate security, capability and stateliness for its duty. A limousine or other high-end vehicle is usually selected.

Due to the high security risk of the passengers, these vehicles are often heavily secured and protected. Vehicles may be armored by the manufacturer or an after-market specialist. In this article the term "armored car" invariably means a reinforced civilian vehicle, not a military vehicle. When carrying an important passenger, state vehicles may be surrounded by a motorcade consisting of police or military personnel. The vehicle's driver might also be from the law enforcement or military pool. The driver of the United States presidential state car is an experienced agent from the Secret Service, the British prime minister is driven by a Specialist Protection officer from the Metropolitan Police Service, and the Canadian prime minister is driven by a Protective Services officer from the RCMP.

A weapons platform is generally any structure, vehicle or mechanism on which a weapon can be installed (via various mounting mechanisms) for optimal stability and performance. The mounted weapons, the platform and all other associated supporting equipments together form the weapon system.

In more general use, a weapons platform could be structured around a gun, such as a gun turret on a ship, or bracing on an aircraft. For example, a jet aircraft is a weapons platform for missiles, bombs or autocannons, and the resultant weapon system is the fighter jet; a motorboat can serve as a weapons platform for automatic weapons, torpedoes and flamethrowers, resulting in weapon systems such as gunboats and fast attack crafts. Land vehicles, either wheeled, tracked or mixed, are also considered weapons platforms for grenade launchers, machine guns, recoilless guns and some missile launchers, which transform the vehicles into weapon systems such as armored cars (such as the Humvee), IFVs and technicals (improvised from civilian pickup trucks). In addition, artificial satellites have been proposed as potential space weapon platforms. These satellites could carry an arsenal of weapons, such as to threaten other countries with the possibility of an orbital nuclear strike (see Rods from God).

The Special Naval Landing Forces (SNLF; Japanese: 海軍特別陸戦隊, romanized: Kaigun Tokubetsu Rikusentai) were standalone naval infantry units in the Imperial Japanese Navy (IJN) and were a part of the IJN land forces. They saw extensive service in the Second Sino-Japanese War and in the Pacific theatre of World War II. While not existing as a dedicated naval infantry branch nor classified as "marines" by the IJN, they functioned as the infantry of the Navy, and engaged in many coastal or amphibious operations, leading to them being referred to as "Imperial marines"or simply "Japanese marines" by a number of Western sources.

The IJN's marine paratroopers were designated as SNLF units, though they were operationally subordinated to the Imperial Japanese Navy Air Service. IJN armored units were generally subordinated to SNLF units and fielded a variety of light tanks, medium tanks and armored cars.

The Violent Struggle (simplified Chinese: 武斗; traditional Chinese: 武鬥; pinyin: wǔdòu), also known as Wudou or Factional Conflicts, refers to the violent conflicts between different factions (mostly of Red Guards and "rebel groups" composed mostly of students and workers) during the Chinese Cultural Revolution (1966–1976). The factional conflicts started in Shanghai and Chongqing in December 1966, and then spread to other areas of China in 1967 which brought the country to the state of civil war. Most violent struggles took place after the power seizure of rebel groups, and gradually grew out of control in 1968, forcing the Central Committee of the Chinese Communist Party as well as the Chinese government to take multiple interventions in the summer of 1968.

During much of the fighting weapons were either acquired by the rebel groups through raids on arms depots or direct support from local military establishments. Weapons used in armed conflicts included some 18.77 million guns (some say 1.877 million), 2.72 million grenades, 14,828 cannons, millions of other ammunitions and even armored cars and tanks. Researchers have pointed out that the death toll in violent struggles ranged from 300 thousand to 500 thousand, while certain documents from the Chinese Communist Party have revealed that 237,000 people were killed and another 7,030,000 were injured or permanently disabled. Notable violent struggles include the battles in Chongqing, in Sichuan, and in Xuzhou.

A periscope is an instrument for observation over, around or through an object, obstacle or condition that prevents direct line-of-sight observation from an observer's current position.

In its simplest form, it consists of an outer case with mirrors at each end set parallel to each other at a 45° angle. This form of periscope, with the addition of two simple lenses, served for observation purposes in the trenches during World War I. Military personnel also use periscopes in some gun turrets and in armoured vehicles.
