An infantry fighting vehicle (IFV), also known as a mechanized infantry combat vehicle (MICV),^[1] is a type of armoured fighting vehicle used to carry infantry into battle and provide direct-fire support. 

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.^[1] 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
