Light tank in the context of "Paratrooper"

An infantry fighting vehicle (IFV), also known as a mechanized infantry combat vehicle (MICV), is a type of armoured fighting vehicle, light tank, and armoured personnel carrier 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.

Infantry fighting vehicles are distinct from general armored personnel carriers (APCs), which are transport vehicles armed only for self-defense and not specifically engineered to fight on their own. IFVs are designed to be more mobile than tanks and are equipped with a rapid-firing autocannon or a large conventional gun; they may include side ports for infantrymen to fire their personal weapons while on board.

A main battle tank (MBT), also known as a battle tank, is a tank that fills the role of armour-protected direct fire and maneuver in many modern armies. Cold War-era development of more powerful engines, better suspension systems and lighter composite armour allowed for the design of a tank that had the firepower of a super-heavy tank, the armour protection of a heavy tank, and the mobility of a light tank, in a package with the weight of a medium tank. The first designated MBT was the British Chieftain tank, which during its development in the 1950s was re-designed as an MBT. Throughout the 1960s and 1970s, the MBT replaced almost all other types of tanks, leaving only some specialist roles to be filled by lighter designs or other types of armoured fighting vehicles.

Main battle tanks are a key component of modern armies. Modern MBTs seldom operate alone, as they are organized into armoured units that include the support of infantry, who may accompany the tanks in infantry fighting vehicles. They are also often supported by surveillance or ground-attack aircraft. The average weight of MBTs varies from country to country. The average weight of Western MBTs is usually greater than that of Russian or Chinese MBTs.

The M1128 mobile gun system (MGS) is an eight-wheeled assault gun of the Stryker family, mounting a 105 mm tank gun, based on the Canadian LAV III light-armored vehicle manufactured by General Dynamics Land Systems for the U.S. Army.

The MGS program emerged after the 1996 cancelation of the Army's M8 armored gun system, the service's planned replacement for the M551 Sheridan light tank.

The Panzer I was a light tank produced by Nazi Germany in the 1930s. Its name is short for Panzerkampfwagen I (German for "armored fighting vehicle mark I"), abbreviated as Pz.Kpfw. I. The tank's official German ordnance inventory designation was Sd.Kfz. 101 ("special purpose vehicle 101").

Design of the Panzer I began in 1932 and mass production began in 1934. Intended only as a training tank to introduce the concept of armored warfare to the German Army, the Panzer I saw combat in Spain during the Spanish Civil War, in Poland, France, the Soviet Union and North Africa during the Second World War, and in China during the Second Sino-Japanese War. Experiences with the Panzer I during the Spanish Civil War helped shape the German Panzerwaffe's invasion of Poland in 1939 and France in 1940. By 1941, the Panzer I chassis design was used as the basis of tank destroyers and assault guns. There were attempts to upgrade the Panzer I throughout its service history, including by foreign nations, to extend the design's lifespan. It continued to serve in the Spanish Armed Forces until 1954.

The Vickers-Carden-Loyd light amphibious tank (designated the A4E11 and A4E12 by the War Office), was a series of British experimental pre-World War II light tanks (resembling tankettes), which, although not taken into British service, were sold to a number of other countries which produced modified versions which were then taken into service.

The Renault FT (frequently referred to in post-World War I literature as the FT-17, FT17, or similar) is a French light tank that was among the most revolutionary and influential tank designs in history. The FT was the first production tank to have its armament within a fully rotating turret. The Renault FT's configuration (crew compartment at the front, engine compartment at the back, and main armament in a revolving turret) became and remains the standard tank layout. Consequently, some armoured warfare historians have called the Renault FT the world's first modern tank.

Over 3,000 Renault FT tanks were manufactured by France, most of them in 1918. After World War I, FT tanks were exported in large numbers. Copies and derivative designs were manufactured in the United States (M1917 light tank), in Italy (Fiat 3000), and in the Soviet Union (T-18 tank). The Renault FT saw combat during the interwar conflicts around the world but was considered obsolete at the outbreak of World War II.

Armoured cavalry are military units using armoured fighting vehicles (AFVs) instead of horses. They began to replace horse cavalry in the heavy shock and the light reconnaissance, skirmishing and exploitation/pursuit roles in most armies commencing after the First World War. In that succeeding capacity, the obsolete name "cavalry" was retained.

Armoured cavalry, or simply armoured units, may be primarily equipped with heavy tanks or lighter and faster light tanks, armoured cars, or even scout cars in the case of what is often known as cavalry scout. Motorized or mechanized infantry may make up a portion of the unit in some countries, supported by either motorized or self-propelled artillery, with possibly airmobile troops on helicopters included.
