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.秦淼辈分高，找这样一个人还真不容易。一时间楚国故地群情激愤，民怨沸腾，当然全都是针对汉国的。Don't forget to save the file.第二次世界大战进入最后阶段，苏联红军步步逼近德意志帝国边境。1944年11月8日夜，有五人飞越前线，前往德国战领区波兰执行特殊的使命。五个人当中只有两个人知道这项任务的具体内容。他们是：格奥格，德国共产党员，1939年逃往苏联；鲍里斯，苏军上校，战前是大学生；恩斯特，前德军陆军上尉，一年前带领被击溃的部队投诚；海内尔，是小组中最年轻的成员，前德国二等工兵，一年前在苏联战场上被俘；杨尼克，波兰游击队员，富于战斗经验。他们确定的降落地点是靠近德国边境的威斯基山角。在飞机接近目的地时被德军发现，飞机中弹，行动小组不得不紧急跳伞。最后准备跳伞的是行动小组主要成员格奥格，他在准备为小组的物资大包挂伞带时不幸中弹。但为了小组的行动，他还是跳了下去……Need what proof can ask district JW, past definitely need high school diploma, this year should have foreign student status certificate, specific by the competent department has the final say
