An infantry fighting vehicle (IFV), also known as a mechanized infantry combat vehicle (MICV), is a type of armoured fighting vehicle used to carry infantry into battle and provide direct-fire support. The 1990 Treaty on Conventional Armed Forces in Europe defines an infantry fighting vehicle as "an armoured combat vehicle which is designed and equipped primarily to transport a combat infantry squad, and which is armed with an integral or organic cannon of at least 20 millimeters calibre and sometimes an antitank missile launcher". IFVs often serve both as the principal weapons system and as the mode of transport for a mechanized infantry unit.
Mechanized infantry are infantry units equipped with armored personnel carriers (APCs) or infantry fighting vehicles (IFVs) for transport and combat.
The BMP-3 is a Soviet and Russian infantry fighting vehicle, successor to the BMP-1 and BMP-2. The abbreviation BMP stands for Boevaya Mashina Pekhoty.
The BMP-2 is an amphibious infantry fighting vehicle introduced in the 1980s in the Soviet Union, following on from the BMP-1 of the 1960s.
The MT-LB is a Soviet multi-purpose, fully amphibious, tracked armored fighting vehicle in use since the 1970s. It was also produced in Poland, where its YaMZ engine was replaced by a Polish 6-cylinder SW 680 diesel engine.
The BMD-2 is a Soviet airborne infantry fighting vehicle, introduced in 1985. It is a variant of BMD-1 with a new turret and changes to the hull. BMD stands for Boyevaya Mashina Desanta.
An armoured train or armored train is a railway train protected with heavy metal plating and which often includes railway wagons armed with artillery, machine guns, and autocannons. Some have also had ports used to fire small arms from the inside of the train, especially in earlier armoured trains. For the most part, they were used during the late 19th and early 20th centuries, when they offered an innovative way to quickly move large amounts of firepower into a new location. Most countries have discontinued their use – road vehicles became much more powerful and offered more flexibility, train tracks proved too vulnerable to sabotage and attacks from the air, and air transportation was an even more flexible way to relocate firepower to a new location. However, there have been occasional uses in the late 20th century and early 21st century. The Russian Federation has used improvised armoured trains in the Second Chechen War (1999–2009) and in its invasion of Ukraine (2022–present).
The BTR-4 "Bucephalus" is an amphibious 8×8 wheeled infantry fighting vehicle (IFV) designed in Ukraine by the Kharkiv Morozov Machine Building Design Bureau.
The Shipunov 2A42 is a Soviet/Russian 30 mm autocannon. It is built by the Tulamashzavod Joint Stock Company and named after A. G. Shipunov.
The Soviet BMP-1 is a tracked, amphibious infantry fighting vehicle (IFV) with a long service history.
The ATOM is a heavy 8×8 infantry fighting vehicle (IFV) jointly developed by the Russian company Petrel and the French company Renault Trucks. The vehicle is established on the basis of the French Véhicule blindé de combat d'infanterie (VBCI) IFV which is produced by Renault. The prototype of the ATOM was first unveiled during the 2013 Russian Arms Expo at Nizhny Tagil, equipped with a unique fighting module.
Armoured Troops are the corps in the Ukrainian Ground Forces, the main striking force of ground troops. They are used primarily in conjunction with mechanized forces in key areas and perform the following tasks:
The 4th Tank Brigade named after Hetman Ivan Vyhovskyi is an armored formation of the Ukrainian Ground Forces.
The Russian armoured train Volga is an armoured train currently in use by Russia in its ongoing invasion of Ukraine in 2022. Unlike its sister train Yenisei, which is built primarily for logistics and refugee ferrying, Volga is primarily used for engineering, reconnaissance, mine clearance, restoration of damaged railway tracks, and escorting cargo within the Ukrainian combat zones.
The Russian armoured train Amur is an armoured train currently in use by Russia in its ongoing invasion of Ukraine in 2022. Unlike the newer trains Yenisei and Volga, Amur was already built long before the Russian invasion of Ukraine. Both Amur and its sister train, Baikal, were reactivated back in 2016, originally for rear-line logistical purposes.
