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.那一身灰衣麻布，也掩不住她的国色芳华，就如同刚才谷中的野花般，虽然开在山野，风采终究不同。睡美人动漫版俗话说，打狗还要看主人，当真自己的面折断了仆人的手指，这直接是往自己脸上打耳光，莫大的耻辱让徐家兄妹愤怒不已。
