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.越战后期，美军上尉威拉德（马丁•辛 Martin Sheen 饰）奉命沿湄公河而上，搜寻脱离美军在柬埔寨建立了自己的王国的科茨（马龙•白兰度 Marlon Brando 饰）上教，将他带回或杀死。科茨上教曾经是美军在越战中的英雄，战功赫赫。然而，忽然有一天，他失踪了。随后，情报指出他在柬埔扎建立了自己的王国，自己的军队，专门反对美军。还有啊，这么些大人在屋里，都坐着不动，倒让个小娃儿端板凳、拿果子，太懒了。　　面对来自恐怖分子的威胁，李警官和卡特再次联手共同作战。在既无恐怖份子下落也不知炸弹藏在何处的情况下，他们一面要争取时间尽快抓到潜伏在香港的恐怖份子，一面要尽快找炸弹的安放位置以便及时解除炸弹威胁。然而由唐·奇德尔、尊龙以及章子怡饰演的恐怖份子却十分狡猾，在目的没有达到的情况下，他们一点点地在拖延时间。眼看上下班的交通高峰期即将来临，正所谓魔高一尺道高一丈，李警官和卡特这对黄金组合在关键时刻抓住了狐狸尾巴，将恐怖分子1935年春，一批红军女兵在强渡嘉陵江后与主力失散，误打误撞闯进了羊坝头地区战场。羊坝头的一场恶战，把失散的女子独立团尖刀班的女兵战士们和红军主力派来的护士班女兵们聚到了一起。为了减少不必要的伤亡，接到红军作战某部的杨团长命令，尖刀班和护士班一起护送伤员，北上寻找红军主力部队。从此一群年轻的女兵们将独自面对险恶环境、狡诈的敌人，开始了一段可歌可泣的长征！一路上，女兵们烧粮仓炸军火、偷电台杀山匪、翻雪山过沼泽，八百里风食露宿，以战养战周旋于敌匪之间。同甘共苦、生死与共，完成了一项项几乎不可能完成的任务！。有血与泪的生死离别，更有缠绵悱恻的爱情；有时不共戴天的仇家，也有不离不弃的亲情，一朵朵铿锵玫瑰在炮火中绽放，又如落樱般在纷飞中凋亡。作为战士，她们谱写了一曲宏伟壮烈的英雄赞歌；作为女兵，她们吟唱了一首婉约凄美的战地情歌……韩信确实是这样认为的，若是采用常规的思路和方式。敬文娘冲李长明笑道：这都过了多少年了，又不是啥见不得人的丑事，有啥不能说的？转向两个儿子，当年你张奶奶要聘菊花，你槐子叔不乐意，说‘菊花再好，那我也不能娶她呀。
