8. Bullets That Shoot Bullets

可以射击子弹的子弹

美国陆军的主动防护系统(APS)是专为士兵打造的一项“星球大战”计划，在设计上，主动防护系统能够保护他们免受火箭推进榴弹以及其它短射程武器的威胁。主动防护系统由雷神公司研制，能够自动探测来袭炮弹而后发射导弹将其摧毁，整个过程只在瞬间完成。如果一切顺利的话，未来美国军车便可在安装少量装甲情况下投入战斗。

Think of the Army's new Active Protection System (APS) as Star Wars for soldiers, designed to protect them from rocket-propelled grenades and other short-range threats. Raytheon's APS will automatically detect an incoming round and then launch a missile to destroy it, all within a split second. If it works, future Army vehicles will be able to head into combat with less armor.
