大口径步枪并不是近些年才出现的。早在二战时期,德国、前苏联就都研制并装备有大口径的反坦克步枪(亦被称为战防枪)。随着坦克防护性能的提高,这种武器很快就失去了效力,也渐渐被人们所淡忘。20世纪80年代以后,随着部队装备、器材、物资的增多,以及在作战申重要性的日益增大,大口径步兵武器重新得到重视,并被赋予新的用途。 Large-caliber rifles did not emerge in recent years. As early as World War II, Germany and the Soviet Union both developed and equipped large-caliber anti-tank rifles (also known as war-defensive guns). With the improvement of tank protection, such weapons soon lose their effectiveness and are gradually forgotten by people. Since the 1980s, with the increase of troop equipment, equipment, materials and the increasing importance in combat operations, large-caliber infantry weapons have been given renewed attention and been given new uses.
