Friendly reminder: The above methods are risky, please use them carefully, and please back up important data during operation.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.　　该剧讲述了一架与地面失去通讯联络且没有任何生命迹象的波音777客机降落在肯尼迪国际机场，美国疾病控制与预防中心生化威胁调查专家奉命赶到现场调查，他发现了一种新型寄生虫，当局解除隔离，一场吸血鬼大灾难即将到来。该剧第一季于2014年7月13日在美国FX电视台播出。自永平十三年十月以来，靖国战争连连，历经三个年头，国力衰退，民不堪命。Step 1: Clarify product positioning and target usersConsole.log (application.
