During the War to Resist US Aggression and Aid Korea, there was a huge disparity in the superiority and inferiority of weapons and equipment between the enemy and us, and some people said that the volunteer army was "called Hanako and the Dragon King than Bao"; especially the air power, the US military threw more than 1,200 fighters of various types into the Korean War, and the volunteer army simply could not compete with it for air supremacy, especially in the early stage of the operation in Korea.
On April 18, 1951, just after dawn, enemy planes were dispatched one by one as usual, and the US air overlord thought that he could come and go as freely as before, and a message from the front line made cadres at all levels nervous: a soldier shot down a US aircraft with a machine gun! Volunteer discipline "no aircraft are allowed to shoot at the air", this is because rifles and other weapons do little damage to the aircraft, not only is it difficult to shoot down the aircraft, but also easy to expose the fire points on the ground.
However, Guan Chonggui saw the tragic scene on the battlefield and could not care about this prohibition, and when he saw the US aircraft dive and strafe, he took the opportunity to grab the machine gun and strafe the aircraft. He pulled the trigger and fired 7 bullets, but did not hit the plane, and the unbelieving Guan Chonggui swept out 7 bullets in one shot! As a result, the US plane suddenly lost its balance in the sky, and before the US pilot could open the parachute after parachuting, he was stabbed to death by the branches of the ground, and the plane he was flying fell and exploded!
The news that Guan Chonggui had shot down the plane with a machine gun soon reached the Volunteer Army headquarters, and at the same time, the handling opinions reported by the regiment also reached the Volunteer Army Headquarters. After reading this, Mr. Peng smiled and said, "We must be resolute in enforcing discipline, and we cannot be rigid, this time the machine gun strikes the planes to give us a long experience, and the enemy planes can be shot down. Not only is it not handled, it is recommended that the Political Department also commend! Subsequently, the headquarters of the Volunteer Army formally decided to award Guan Qigui the title of "first-class combat hero", and Peng Dehuai personally wrote down a warrant: Comrade Guan Chonggui was promoted from deputy squad leader to deputy company commander.
