It takes advantage of a defect in the implementation of TCP protocol. By sending a large number of attack messages with forged source addresses to the ports where the network service is located, it may cause the half-open connection queue in the target server to be full, thus preventing other legitimate users from accessing. This kind of attack was discovered as early as 1996, but it still shows great vitality. Many operating systems, even firewalls and routers, cannot effectively defend against this kind of attack, and it is very difficult to trace it because it can easily forge the source address. Its packet characteristics are usually that the source sends a large number of SYN packets and lacks the last handshake ACK reply of the three handshakes.身经百战的克里斯下士（Josh Kelly 饰）晋升为小队的指挥官，该小队的下一个任务是给位于塔利班控制边缘地区的前线哨所提供补给。当车队行经敌对的赫尔德曼省时，他们遇到了寻求帮助的海豹突击队，双方将合作完成一项重要任务——护送一名因反抗塔利班而闻名的妇女逃离该国...没有坦克装甲车和空中支援，克里斯下士和他的团队必须鼓足全部勇气，拼尽所有弹药，横穿这个被战争蹂躏的国家，直至护送该妇女到安全地点关中谋略你们已经看过了，只要能够出巴蜀，平定关中指日可待。泰德寻觅多年的真命天女、万众期待的老妈，终于出现了！　　金炳哲饰演大马集团的核心干部郑北东，他被称为“带着电脑的推土机”，具备耐心和观察力。他成为千里马超市的新店长，投入复兴超市的热血战场。他是一个风风火火，直来直往，非常自信且不屈不挠，有着极高自尊心的男人。虽然经常被说看上去像个醉汉，但其实是中年男人一枝花。
