Infantry Fighting Vehicle

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 fire support.

IFVs are similar to armoured personnel carriers (APCs), designed to transport a section or squad of infantry (generally between five and ten men) and their equipment. They are differentiated from APCs—which are purely transport vehicles, armed only for self-defence—because they are designed to give direct fire support to the dismounted infantry and so usually have significantly enhanced armament. IFVs also often have improved armour and some have firing ports (allowing the infantry to fire personal weapons while mounted).

They are typically armed with an autocannon of 20 to 40mm calibre, 7.62mm machine guns and possibly with anti-tank missiles (ATGMs) and/or surface-to-air missiles. IFVs are usually tracked, but some wheeled vehicles fall into this category, too. IFVs are generally much less heavily armed and armoured than main battle tanks, but they sometimes carry missiles, such as the NATO TOW missile and Soviet Bastion which offer a significant threat to tanks.
