In the late 1950s, Chinese mainland's airspace was frequently invaded by the enemy. The central government decided to buy Sam -2 surface-to-air missiles from the Soviet Union and set up an air force surface-to-air missile unit, thus beginning a new era of fighting against the enemy. A group of outstanding officers and men from all directions were ordered to be transferred to this mysterious force code-named "543". Battalion Commander Xiao Zhanwu led a group of good soldier with their own characteristics to form Hero Battalion II, and made outstanding contributions in the future.
The whole battalion carried forward the fighting spirit of "one gun for the whole battalion", withstood the pressure of target failure and shot down RB-57D in one fell swoop, setting a record for shooting down a high-altitude reconnaissance plane with surface-to-air missiles in the history of world air defense. At the most difficult moment of building the army, the enemy resumed reconnaissance of the mainland. Faced with professional and technical problems, uneven casualties, shortage of missile spare parts and other unfavorable factors, the Second Battalion resolutely assumed the heavy responsibility of missile ambush and began an arduous field battle. In the end, the whole battalion overcame many difficulties and shot down many enemy U-2 high-altitude reconnaissance planes in one fell swoop, creating an unprecedented brilliant record.
Yue Zhenhua's TV plays, as works of art, don't summarize his achievements statistically, and the audience is often attracted by the ups and downs of stories and ignores his greatness. He was the first person in the world to shoot down an enemy plane with a surface-to-air missile. He has known missiles for less than a year, and he has set a precedent in the history of world air defense. He is also the person who shot down the U2 high-altitude reconnaissance plane the most in the world, and is called the "U-2 Terminator", which shocked the western world and attracted global attention.
