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.
