At the most dangerous time, even mines are thrown out, At that time, the 'round head' anti-infantry mine (still referring to Type 72 anti-infantry mine) had a 'bolt' (i.e. Safety ring) under it. Just pull it out, Throw it out like a grenade, But more powerful than a grenade, As soon as a large area is blown up, But because it is heavier, More than three grenades, Therefore, those with weak throwing ability generally dare not use it like this. Because I'm afraid I can't throw it out of the safe range and blow it up to myself, But fortunately, whatever it is, As long as you want to attack, It must be an attack on the ground, We have a great advantage from a high position. Throwing explosives from high to low can increase the throwing distance, Even if you can't throw it far away, After landing, you can also roll down a little further distance. Therefore, some comrades who throw grenades not far away can also throw mines away from a safe distance to strike the enemy. Then there is the explosive cartridge, The vast majority of people can't throw out three pieces of explosive cartridges in one go like a company commander. And it is too wasteful to throw them all like that, So he threw the explosive cartridges out one by one, When the "big grenade" is used, The reason why I dare to do this and make such "rich" moves is because there are not many others in our positions, that is, grenades, mines and explosive cartridges are plenty of explosives, and many to "tube enough", thanks to these, otherwise in the period of time without artillery support, the Vietnamese army's offensive forces increased several times, and the guns in hand alone could not hold up completely.
