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.Amazon宣布续订《#无垠的太空# The Expanse》第五季！据外媒报道,Netflix还将制作一个关联动画电影《巫师：狼之噩梦（TheWitcher:NightmareoftheWolf）》。《巫师：狼之噩梦》是一个电影项目,编剧是BeauDeMayo。DeMayo是《巫师》电视剧第三集BetrayerMoon的编剧,同时也将是《巫师》第二季8集中其中一集的编剧。There are eleven behavioral patterns (13-23): policy pattern, template method pattern, observer pattern, iterative sub-pattern, responsibility chain pattern, command pattern, memo pattern, state pattern, visitor pattern, intermediary pattern and interpreter pattern.许许多多的网友带着激动的心情，点开陈启留下的链接，因为天启的话太吸引人了。Ghost drug, ghost drug G and explosive mushroom are all available at the beginning and last until the end of the mission or the cat car.对欧洲人可不好玩。
