Armoured personnel carrier in the context of "Mechanised infantry"

Motorized infantry is infantry that is transported by trucks or other motor vehicles. It is distinguished from mechanized infantry, which is carried in armoured personnel carriers or infantry fighting vehicles, and from light infantry, which can typically operate independently from supporting elements and vehicles for relatively long periods and may be airborne.

Mechanized infantry are infantry units equipped with armored personnel carriers (APCs) or infantry fighting vehicles (IFVs) for transport and combat (see also armoured corps).

As defined by the United States Army, mechanized infantry is distinguished from motorized infantry in that its vehicles provide a degree of armor protection and armament for use in combat, whereas motorized infantry are provided with "soft-skinned" wheeled vehicles for transportation only. Most APCs and IFVs are fully tracked or are all-wheel drive vehicles (6×6 or 8×8), for mobility across rough ground. Some militaries distinguish between mechanized and armored (or armoured) infantry, designating troops carried by APCs as mechanized and those in IFVs as armored.

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 For example, relatively lightly armed armoured personnel carriers were largely superseded by infantry fighting vehicles with much heavier armament in a similar role.

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 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 armoured recovery vehicle (ARV) is typically a powerful tank or armoured personnel carrier (APC) chassis modified for use during combat for military vehicle recovery (towing) or repair of battle-damaged, stuck, and/or inoperable armoured fighting vehicles, such as tanks and armoured personnel carriers. Most ARVs have motorized tracks, like a tank or bulldozer, enabling the ARV to operate on uneven ground. The term "armoured repair and recovery vehicle" (ARRV) is also used.

ARVs may have winches, jibs, cranes, and/or bulldozer blades to aid in tank recovery. Typically, any specialized lifting and recovery equipment replaces the turret and cannon found on a battle tank. ARVs may in some cases have electric generators, blowtorches, chainsaws and fuel pumps to help with recovery operations, or spare parts, to facilitate field repairs. Some ARVs have a spade component to anchor the vehicle when it is towing or lifting. Since most ARVs are based on tank or APC chassis, they have an armoured crew cockpit and engine, which means that ARVs can be operated in combat conditions. Rarely, an ARV may be armed, such as some M32s, which have an 81 mm mortar for screening purposes, and the M88, which has a .50 cal heavy machine gun. One WWII M4 Sherman-based ARV had a dummy gun installed where the turret would normally go.

The Ivan Rogov class, Soviet designation Project 1174 Nosorog (Rhino), is a class of landing ships (large landing ship in Soviet classification) built in the Soviet Union. The ships were built as a part of expansion of the Soviet Navy's amphibious warfare capabilities in the 1970s.

Project 1174 has both bow ramp and well deck; it may operate as either a LST or as a LPD. A typical load is one battalion of 520 marines and 25 tanks. Up to 53 tanks or 80 armoured personnel carriers may be carried if the well deck is used for ground vehicle parking. In total, 2,500 tons of cargo may be carried.
