The main body of this weapon, also known as the explosive barrel, is an empty gasoline tank. After the propellant is filled, put the disc-shaped explosive charge into it, and then ignite the propellant, and you can throw the explosive charge of 10 kg to the distance of 150-200 meters. The caliber of this weapon is absolutely amazing-how thick the barrel is, how big the caliber is, and the strong explosion impact generated by the huge amount of explosives will blow up everywhere, bunkers and people. Many enemies who have been blown down often can't find any wounds, but they have shed seven holes of blood, which is scary. After understanding this situation, the Kuomintang army simply called this kind of thing "heartless cannon."
The petrol tank gun was a special weapon made by the People's Liberation Army during the War of Liberation, because at that time, the People's Liberation Army did not have its own military industry and seized few guns. In the war, it suffered great losses because of the lack of heavy weapons. In order to make up for the lack of firepower, the PLA created a weapon that ordered the enemy to be frightened at that time, that is, a cannon made of petrol cans. The main structure of this gun is divided into three parts, namely, gasoline tank, explosive bag and gunpowder. At that time, our army gave this kind of gasoline tank gun a domineering name, called "flying thunder gun tube". The flying thunder gun tube can throw about 10 kg of explosives to 150-200 meters to kill the enemy.
The lethality is limited. Because the ejected explosive charge can't produce dense metal killing fragments like shells, it can only kill the enemy by the shock wave generated by explosive explosion, and its killing radius and killing effect can be imagined.
