Top Secret 543

In the late 1950s, mainland China's airspace was frequently invaded by enemies. The central government decided to purchase SAM-2 surface-to-air missiles from the Soviet Union and establish an air force surface-to-air missile force. This began a new era of combat against the enemy. A group of outstanding officers and soldiers from all over the world were ordered to join this mysterious force code-named "543". Battalion Commander Xiao Zhanwu led a group of outstanding soldiers with their own characteristics to form the second battalion of heroes who would make repeated military exploits in the future. The whole battalion carried forward the fighting spirit of "one gun for the entire battalion" and withstood the pressure of failed target shooting, shooting down the RB-57D in one fell swoop, setting a record in the world's air defense history for shooting down a high-altitude reconnaissance aircraft with a surface-to-air missile. At the most difficult moment of troop building, the enemy resumed its deep reconnaissance of the mainland. Faced with technical difficulties, incomplete casualties, and shortages of missile spare parts and other unfavorable factors, Erying resolutely assumed the responsibility of missile ambush and began the arduous field operations. In the end, the entire battalion overcame numerous difficulties and shot down multiple enemy U-2 high-altitude reconnaissance aircraft in one fell swoop, creating an unprecedented and brilliant record.
