个人防卫武器(Personal defenseweapon-PDW),有时也被叫做单兵自卫武器(Individual defense weapon-IDW),是美国在1986年提出发展新型、可连发、操作简易、尺寸和重量不大于当时制式冲锋枪的轻型枪械计划,来替换当时北约成员国所装备的制式冲锋枪及某程度地代替手枪作为非前线军人的防卫性武器,并要求优于当时制式冲锋枪远射性能和贯力。人机功效、穿甲性能和有效射程是PDW的3大要素,当今各国对于PDW的发展侧重点各有不同,笔者的观点是人机功效>穿甲性能>有效射程。 Personal defenseweapon (PDW), also sometimes referred to as the Individual Defense Weapon (IDW), was proposed by the United States in 1986 to develop a new, continuous-fire, easy-to-use, sized and weight- To replace the standard submachine guns and the defensive weapons that some NATO member countries were replacing as non-front-line military personnel, and demanded that they should be superior to the long-range submarine-launched submachine gun at the time. Human-machine effect, piercing performance and effective range are the three major elements of PDW. Nowadays countries focus on the development of PDW each have different points, the author’s point of view is man-machine effect> armor performance> effective range.
