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.等待罗宾逊一家的还有更多危险和冒险！随着 木星 2 号在神秘的海洋星球上搁浅，没有了他们心爱的机器人，罗宾逊一家必须与心思叵测且擅长操纵他人的史密斯医生以及富有魅力的丹·韦斯特协力合作，将其带回坚毅号并与其他殖民者汇合。可是他们很快发现一切都不是看起来的那样。他们努力寻找机器人的下落，以及通往半人马座阿尔法星安全通道的关键线索，出现了一系列令人难以置信的新威胁和出乎意料的发现。他们将不遗余力保护家人安全…毕竟，生存下来是罗宾逊一家的专长。Updated March 13老光棍马四辈饿急了跑到桃花村偷包谷，被民兵抓住游街示众。送往公社途中，土崖塌方，将桃花村姑娘高枝枝埋在底下，马四辈奋不顾身跳崖抢救。A work of making history在世界上最神奇的梦幻岛上面，除了小飞侠彼得潘和奇妙仙子之外，还有许多神奇的故事！且看勇敢的少年杰克，要如何跟虎克船长展开海盗大对抗！儿童海盗的首领杰克，常常遭遇虎克船长的威胁，为了确保秘密基地的安全，同时顺利完成各种海盗任务，他必须靠着和队员琦琦、阿比以及瞭望员鹦鹉史卡利的合作，才能惊险度过每一次难关。
