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.TelecommunicationsRelated Articles:(2) There are seven structural modes: adapter mode, decorator mode, agent mode, appearance mode, bridging mode, combination mode and element sharing mode.是吗？要不你送我一朵？萧月婷向丁洋伸出了手。讲述埃利奥特和他们所有的森林朋友一个全新的冒险，Boog他决定自己旅行，一个酷似马戏团的灰熊，接管他的位置。 布格的朋友准备把他从俄国旅行马戏团带回家。一连串有趣的事情。
