"A Bloody Unknown River" tells the story of a division and detachment of the Volunteers who hit the American heavy artillery battalion behind enemy lines. From the very beginning, the film reflects the high-burning combat power of the volunteers from the perspective of the US military. Du Chuan, a volunteer sniper, shot and killed the colonel sitting in the jeep from a distance under the nose of the American sniper team.

You know, at that time, the speed of the jeep reached 50 miles per hour, and it was located in a mountainous area, and the environment was complex and the difficulty could be imagined. The American sniper who was beaten in the face was puzzled by Du Chuan's sniper position. According to the ballistics formula, the accuracy decreases by 2.5 cm for every 90 m increase in shooting distance, and the trajectory is also affected by wind, gravity, humidity and other factors. Du Chuan can kill himself with one shot. Obviously, he has excellent sniper skills.

Du Chuan was both a "Shen Du cannon" and an ordinary soldier of the Volunteers, which was determined by the situation at that time. 195 1 in April, 2008, the volunteers went through five battles with Korean soldiers and civilians, and formed a north-south confrontation with the "United Nations Army" led by the US and South Korean armies near the 38th parallel. Volunteers built a complete tunnel fortification integrating attack and defense, mobility, life and medical care, and formed a defense support system with tunnels as the backbone and trenches as the link.

In view of the fact that the distance between the fortifications of the two sides is only 400-500m, and the nearest adjacent position is only100m, both of which are within the range of various caliber guns, the Volunteer Command believes that small victories can be accumulated by means of "zero-knocking candy" and puts forward the slogan of "turning dead positions into living positions to facilitate blood circulation". After the actual combat test, the sniper tactical system of the volunteers came into being.

Equipment of two armies

The film restored the equipment gap between the two sides in the Korean War. Major of American Vulture Squad is equipped with M 1C Garland sniper rifle, with a caliber of 7.62mm, a gun length of 1 107mm and a muzzle velocity of 865 m/s. This gun is equipped with 2.5 times sight, muzzle flame suppression, cheek pad and other special accessories, which is a sniper rifle commonly used by the US military in World War II. Because the bullet contains eight bullets, it is called "Big Eight".

The equipment of the us military does not stop there. In the movie, the third platoon met the American army for the first time and was savagely strafed by the M2 Browning heavy machine gun. In fact, experienced American machine gunners use M2 Browning heavy machine guns with large caliber and low power sight. Taking advantage of12.7× 99mm bullet's high muzzle velocity and great lethality, we carried out some sniper shooting on volunteers who were away from1800m.

During the period of 1942, affected by the Pacific War, the US military established a reconnaissance-sniper training center in California Army Barracks. Through "base training", snipers are trained. The vulture squad in the film is a professional sniper squad composed of snipers, observers and reserve players, which poses a great threat to the volunteer detachment.
