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.因为哥哥们说了，要是得了头名，就带他们去下塘集逛。After completing the three-way handshake, the client and the server begin to transfer data.
