Original sentence: 50 cal armour-piercing bullets and 20-23 mm caliber autocannons across the frontal arc as well as from light shell fragments at distances between 500 m and 800 m (the distance of infantrymen dismounting onto the battlefield during an attack).Mechanized infantry tactics during the 1950s hadn't advanced past World War II methods where APCs were used as "battle taxis"; they brought their infantry up to the frontline where they then dismounted and fought on foot while the APC provided covering and suppressive fire from its on-board armament.Side armour should be capable of withstanding 7.62 mm armor-piercing bullets from a distance of 75 m
