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.1905年，从小离开祖国的韩裔美国军官因外交任务重返朝鲜。在过去作为孤儿奴僕的痛苦中挣扎时，他却发现自己与一名贵族的女儿，陷入了複杂的关系。《孤单又灿烂的神 — 鬼怪》创作团队最新力作，《阳光先生》将于7月7日在Netflix首播。郑氏只觉得五内俱崩，泪如雨下。侠盗楚留香为拯救灾民，受人雇佣，来到云来客栈盗取“天下第一美女”鱼尺素的心，不想却被鱼尺素的经历感动。If there is no low-temperature slow cooking machine, steak practice is basically the same, and with Sous Vide, it is about the same to heat each side for 30S with a color on the surface.
