"This' knowledge 'is out of ammunition, Before, we used ordinary bullets to hit these big wasps. So the killing efficiency is not high, After hitting them with '74 jets', We found that they were very afraid of fire. So he took out all the tracer armour-piercing bombs that were pressed at the bottom of the box. These bullets have three more functions than ordinary bullets: luminous, armor piercing and burning. This kind of bullet is mainly to use the tracer function to provide target indication for friendly fire. It works best at night, Then there is the use of this kind of ammunition to collect fire and shoot at the ammunition and fuel accumulation areas of the Vietnamese army. Because they can wear armour, So it can break through some relatively hard shells, Like car doors, Oil drum skins and so on, Then blow off inflammable and explosive substances such as ammunition and gasoline, In order to destroy the enemy's military materials, Because the above assumption was that the Vietnamese army might fight with our army in positional warfare, It is the kind of positional warfare in which the two sides fight each other. That's why so many of these munitions are being distributed, But this is not the case, The Vietnamese army did not have the patience to build positions to fight our army. But directly launched the attack, The envisioned positional warfare turned into defensive warfare, That's it, In the battle before position 149, there was basically no place where the three functions I mentioned above could be used. In this way, those traced armour-piercing firebombs are basically useless. In order not to let them get in the way, they were piled up at the bottom of all the ammunition. At that time, they were taken out at the right time. We used the battle gap to replace all the ordinary bullets with traced armour-piercing firebombs to hit the second batch of big wasps. The effect was not good.
