context_page_description: An infantry fighting vehicle, also known as a mechanized infantry combat vehicle, 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.
  Infantry fighting vehicles are distinct from armored personnel carriers, 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.

  Infantry fighting vehicles are distinct from 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.  
  The IFV rapidly gained popularity with armies worldwide due to a demand for vehicles with high firepower that were less expensive and easier to maintain than tanks. Nevertheless, it did not supersede the APC concept altogether, due to the latter's continued usefulness in specialized roles. Some armies continue to maintain fleets of both IFVs and APCs.
