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.韩信心中感慨，他知道吕雉写信来不是报丧的，将如此隐秘的事情告知自己，必然是有用意的。忙乱中，板栗见小葱来回在人群中扫视，忽然想起李敬文已经走了，急忙上前低声道：妹妹，敬文先走了。这次007对手是臭名昭著的国际恐怖分子雷纳德。为了垄断石油供给权，雷纳德杀害了石油大亨罗伯爵士，当然他也不会放过罗伯爵士的继承人——美丽的依蕾克屈，这个狂人甚至威胁说要在土耳其巨大的输油管道里引发核爆炸。于是007必须驾着高速快艇从西班牙比尔堡的奈维河岸到伦敦的泰晤士河边，再穿越苏格兰的高地，冒着几乎不可能生还的危险去保护罗伯爵士队唯一继承人、粉碎雷纳德的阴谋。连场大战一触即发！The matter of.
