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.What is DDoS?Three, the use of star endorsements to pay attention to its periodicity, identity解放军某部宣传处干事、高干子弟赵蒙生，一心想调回城市。自卫反击战前夕，他凭借母亲吴爽的关系，怀着曲线调动的目的，临时下放到某部九连任副指导员。忿不平，替连长买好车票，催他起程。可是，九连接到开赴前线的命令。梁三喜失去了探亲的机会，赵蒙生却接到回城的调令。全连战士哗然，梁三喜严厉斥责了赵蒙生临阵脱逃的可耻行为。舆论的压力迫使赵蒙生上了前线。吴爽不顾军情紧急，竟动用前线专用电话，要求雷军长将赵蒙生调离前线，当即遭到雷军长的谴责。 　　九连担任穿插任务。鏖战中，一个个战友为国捐驱，梁三喜为掩护赵蒙生而牺牲；“小北京”因臭弹未发而身亡。赵蒙生在血与火的洗礼中，经受了考验。 　　战后，在清理战友的遗物时，梁三喜留下的一张要家属归还620元的欠帐单，使赵蒙生震惊不已。烈士的家属纷纷来到驻地，梁三喜的母亲和玉秀用抚恤金及卖猪换来的钱，还清了三喜因家里困难向战友借的债。这一高尚的行动震撼了人们的心灵，赵蒙生和战友们含着热泪，列队向烈士的家属，举手致以最崇高的敬礼。美第奇家族的传奇历史，由达斯汀·霍夫曼和理查·麦登领衔主演9.
