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.康纳家庭生活第三季辽沈战役前夕，隐藏在北平警察局里的地下党员郑朝阳因叛徒出卖不得已紧急撤退。同时带走了国民党精心准备的地下潜伏名单。昭和五十八年，六月。寒蝉鸣泣之时。讲述男主角Ned Chipley出生因发生意外而时智力受限，在第四次尝试加入海军失败后，他和离家出走的少女Tally Petersen组队，监视一群年轻人，他俩错认为他们是恐怖分子，不幸与国土安全局扯上关系。抗战结束，中共派人到东北创办航校组建空军。戴笠知悉情况后，派出特工“13号”，实施“死鹰”行动，企图剿杀中共空军雏鹰。一场国共间惊心动魄的明争暗斗拉开帷幕。
