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.Hello, no, this standard is mobile network standard, telecom standard is cdma, mobile phone support cdma standard can be used to install telecom mobile phone cardThe eldest son of the Lins 01大一些的孩子都会意，于是不再说这事，只用心对付桌上的各色羊肉羊杂。主人公・25岁的末永圣是一名乡村中学的语文老师，她和恋人已经有了婚约，目前两人处于异地恋爱的状态。但第一次担任班主任的她却对比她小11岁的美少年黑岩晶动了心。巴蜀栈道成功重建，如今可以往来的也只有一条陈仓小道。
