看见他眼中满是血色，想来已经很久没有好好休息过来。板栗气得对一只大黑狗骂道：不就拉个车，你慌啥？整天见了我就摇头摆尾，要你干一点正事就不成了。他们都觉得，大人是因为二姐姐的事操心。二十世纪五十年代末，中国大陆的领空频频遭到敌方侵扰，中央决定向苏联购买萨姆－2型地对空导弹，组建空军地空导弹部队，从此开始了对敌作战的崭新时代。一批来自四面八方的优秀官兵奉命调入这支代号为“543”的神秘部队，营长肖占武带领着一帮各具特色的优秀战士组建成为日后屡立战功的英雄二营。全营发扬“全营一杆枪”的战斗精神，顶住打靶失败的压力，一举击落RB-57D，首创世界防空史用地对空导弹击落高空侦察机的纪录。正在部队建设最困难的时刻，敌人恢复了对大陆纵深的侦察。面对专业技术难题、人员伤亡不整、导弹零配件短缺等不利因素，二营毅然承担起导弹伏击的重任，开始了艰苦卓绝的野外作战。最终，全营克服了重重困难，一举击落了多架敌U-2高空侦察机，创造了史无前例的辉煌战绩。儿时的兄弟,为了共同的情谊重新聚集；青春岁月里的梦想不会因为岁月的蹉跎而泯灭，在梦想光环下,青春的悸动,对爱情的懵懂，混杂着现实的残酷，情与义的五味杂陈在这个夏天瞬间发酵！In addition, As Zhang Xiaobo said, On the front line at that time, Wearing or not wearing a helmet is a "choice", Because Vietnam is located in Southeast Asia, The climate is hot and humid, Helmets are heavy and airtight, Wearing it is very easy to cause heatstroke, Particularly in fast maneuvers, This is the easiest way to do strenuous activities such as running. Therefore, in order for the troops to fight more efficiently, There would be no mandatory order for everyone to wear a helmet, If you don't want to wear it, you can choose to wear a cloth cap with eaves. So in the vast majority of relevant historical photos, Among our troops participating in the war, The highest percentage of helmets is worn by artillery, It is mainly used to defend the fragments of enemy artillery and various hard objects brought up by explosions in artillery warfare. Even some border militiamen wore helmets in large numbers, On the contrary, the impact is at the forefront, Infantry units carrying out a large number of mobile combat missions are rarely worn, Investigate its reason, It is for the infantry troops to carry out large-scale interspersed operations frequently. Exercise is enormous, It is really inconvenient to wear helmets, This approach has both advantages and disadvantages, It is not good to judge right or wrong here, but when facing such a horrible "killer bee" on the ground on 149, it is regrettable and regrettable that the heavy casualties caused by the low wearing rate of helmets have to be said. If they had worn helmets instead of military caps like Zhang Xiaobo, the casualties caused by the sting attack of "killer bee" would have been much smaller.但也正是如此，各个影视公司都在扎堆拍摄武侠剧。
