One last thing on this subject, The 7.62 mm traced armour-piercing firebombs fired by the 81-1 family, Although the name is a little long, But compared with ordinary munitions, The difference is still well understood: Tracing and burning are simple, Is to add two corresponding drugs, The armor piercing is to replace the steel core behind the bullet's brass back armor (also known as bullet head) with a harder tungsten alloy core with stronger penetration to hard targets. The latter is also the tail-stabilized shelling penetrator used on the third generation of modern main battle tanks (abbreviation: APFSDS) is one of the two main materials (the other is the notorious, highly radioactive depleted uranium penetrator core, The user country is mainly the United States, while China mainly uses tungsten alloy penetrators, Less pollution and better performance, The United States does not need to. First, the United States does not pass the standard of tungsten treatment technology. Far from the level of our country, Secondly, the United States is a tungsten-poor country. It also wants to fully use tungsten alloy bombs, But it can't be used, But as a nuclear Power, There is a lot of depleted uranium as nuclear waste, so depleted uranium is selected as a substitute. As for tungsten alloy and depleted uranium, after putting aside the key additional condition of radioactive pollution, the pure question of who is better in armour-piercing performance is not directly related to this article, so it will not be described in detail).When learning design patterns, there are some skills that can help you quickly understand design patterns.本剧由喜剧演员Jack Rooke创作、编剧和担任旁白，改编自Rooke的获奖现场喜剧作品《Good Grief》《Happy Hour》《Love Letters》。不过无诸走的是番邑，绕道而行。娘只要想想，要是咱们住在西北边关，那对敌人该有多恨哪。"The first few hours of the battle were the same as before, We use all kinds of weapons in our hands in our positions. Strike the attacking Vietnamese troops, The exchange of fire was very intense, The front of the position was covered with the bodies of the Vietnamese army. We also have a lot of wounded on our side, However, after all, it is based on strong fortifications. More wounds, less deaths, In particular, the wounded are mainly minor, All of them can continue to fight without getting off the line of fire. At that time, my monitor was quite happy. If you play like this, There's not much pressure to hold position 149, The Vietnamese army that could fight could not even get close 400 meters away from the front of the position, As a result, it was only over an hour after he said this. I remember it was one or two o'clock in the afternoon. Something is wrong, The left and right wings of the position, It's two sparse rain forests, The positive was the same, But before the war, in order to facilitate the offensive forces to assault, All of them have been cut down by Vietnamese troops, But it also broadens our horizons, However, it is still unclear what is going on in the rainforest on both sides. Just when something was wrong, First I heard a "buzzing" sound inside, At first it was a little bit, Later it grew bigger and bigger, At last it was so big that it could almost cover the shot when it was fired. No one in our position knows what's going on, All of them stretched out their heads and looked in the direction of the sound. When the "buzzing" sound reached its peak, they saw that a large area of flying insects flew vertically from the rainforest on both wings. If the number were small, whether the sound or flying insects could not be heard or seen at this distance, but now they could hear clearly. 《战争与和平》是俄国作家列夫·托尔斯泰（Leo Tolstoy）的大部头名著，小说通过对安德烈、彼埃尔、娜塔莎三人在1812年俄国卫国战争前后的经历，展示了当时俄国社会的风貌、反映了1805年至1820年间的许多重大历史事件。
