At that tail of the warhead, the drag armour-piercing firebomb is filled with a drag agent and a fireagent, Under the pressure of propellant propelling warhead, it will spontaneously ignite to produce open flame, So it can break through the oil drum and ignite or detonate the gasoline. However, the old-fashioned traced armour-piercing firebombs have obvious trajectories due to traced light when they are launched. Therefore, it is very easy to expose oneself while pointing targets to friendly forces. Therefore, the new tracer armour-piercing firebombs now equipped all start to burn and emit light only after the projectile flies out of the muzzle for a certain distance (the generally set safe distance is 100 meters, which makes it impossible for the enemy to judge the firing position with tracer ammunition, while targets within 100 meters do not need to be indicated by tracer), The principle is generally to ignite the tracer and combustion agent carried by the projectile by accumulating the heat generated by the warhead's friction with the air after flying for a certain distance to a certain extent.爱丽丝是一个害羞的青少年，为了赢得父亲的爱，她成为了黑手党组织最年轻的成员。十年前，平海站派出所民警赵鹏程在执勤时遭遇持枪嫌疑人，开枪时“哑火”，关键时刻师傅徐雷挡在他面前击毙罪犯也中弹致残，这使赵鹏程在家庭和工作上背负上沉重的精神压力。十年后，平海所值班室发生了“走火”事故。当事民警刘长路顾及他人前途决定隐瞒不报，然目击“走火”的赵鹏程却深陷情与理的抉择中。“走火”事件被人举报，引发平海所的人际纠葛。办案时，赵鹏程和刘长路遭遇袭警，刘长路开枪警告时，一颗子弹误伤路人，造成意外“失火”，由此被告上法庭。案件引发警察用枪法律层面上的思考，律师迟玉和赵鹏程找到关键证据，洗清刘长路罪名，赵鹏程向刘长路坦承是他举报了“走火”，却遭到大家误解。当再次面对枪口，赵鹏程挡在刘长路面前秒杀罪犯，赵鹏程的“开火”打碎了当年“哑火”的精神枷锁，让大家理解了他举报“走火”的正确意义。一群任性的青少年在野外新兵训练营必须为他们的生命与一个无情的吸血外星人的攻击斗争我历无量量劫，照十方国无所障碍。凯叔讲故事是一个专门给孩子讲睡前故事的微信公众号。凯叔名叫王凯，是一名自媒体人。凯叔讲故事，不止讲给孩子的故事，对于大人来说，同样是一种童年的回忆。去机场接朋友思缤的英珠，与从美国进修回来的小学同学——潇洒幽默、极俱才能的承振邂逅相遇，当承振想起小时候暗恋英珠的情景，暗地勾起了他对儿时美好回忆。此时，英珠已有了相处八年、本性善良的恋人——广播制作人东锡；承振也有一位外貌迷人、性格奔放的女友——美大毕业的摄影师美艳。而英珠、美艳、思缤恰恰是学生时代最要好的同窗。性格温和的东锡，由于受英珠的推托和母亲的阻挠，迟迟未能与英珠达成婚约。承振忆起小时残存的美好片断及父母离异带来的痛苦，觉得只有英珠考勤能唤回他美好的一切，于是……
