第一次世界大战中坦克的出现,给交战双方的步兵带来前所未有的威胁。在最初的恐惧过后,人们开始寻找打击坦克的方法。当时坦克的装甲板较薄,大口径枪弹就可能击穿,因此各国都相继开发出大口径反坦克枪作为步兵反坦克武 The emergence of tanks in the First World War brought unprecedented threats to the infantry of the warring parties. After the initial fear, people started looking for ways to fight tanks. At that time, the armor plates of the tanks were thin and large-caliber gun shells could break down. As a result, all countries have successively developed large-caliber anti-tank guns as infantry anti-tank weapons.
