China has a very large land area, and the climate and environment of various regions are very different. Except for the polar climate, the climates of other parts of the world are in China. Therefore, the requirements for weapons in this diverse environment are very high, especially for individual soldiers. The reliability of the weapon. Therefore, China has strict selection criteria when selecting guns, one of which is the famous "Yellow River Water". In fact, all countries will conduct mechanical reliability testing, accuracy testing, and environmental testing when selecting guns, but environmental testing is the most important one. For example, the AK rifle is known for its simplicity, durability and environmental adaptability, while the M-16 rifle of the U.S. Army in the Vietnam War has been criticized for being too sophisticated and causing frequent failures in tropical environments.
Like India’s tanks imported from Russia, when they arrive in India, they often fail due to heat dissipation problems. Because Russia is in a cold area at high latitudes, the environment is very cold, so Maozi doesn’t need to pay too much attention to the heat dissipation of the tank, but when it comes to India in the tropics, It’s not the same. It’s just as hot as it is in normal weather, so it’s not a fault. Therefore, weapons must be tested by environmental tests before they are put into service, otherwise they will be incompatible with environmental problems like Indian tanks.
Compared with other countries’ simple environment, China’s environment is very different. There are high-cold environment in the plateau, tropical and subtropical high-temperature and high-humidity environment in the south, the dry desert environment in the northwest, and the dry and cold environment in the north. When finalizing the design, it is necessary to accept the test of these local environments. China has very high requirements for individual weapons. The most stringent one is the "Yellow River Water Test". During the test, 0.08~0.2 mm of sand is poured into the water, and the concentration per cubic meter is 1.5kg. ~3Kg, then soak in the flowing sand for 10-20 minutes before shooting. The purpose of this is to simulate whether the reliability of guns will deteriorate when the guns are soaked in rivers with high sediment content during armed swimming. The river with the largest sediment content in China is the Yellow River, which was per cubic meter at that time. The cement sand content exceeds 30kg.
In the 1980s, when China was developing a new generation of weapons, it tested foreign weapons in the Yellow River, including the famous Austrian AUG assault rifle, the American AR series rifle, and Singapore’s "Invincible 100". Among them, the American M-4 assault rifle was tested in wind and sand conditions in China. In the test of 60,000 rounds, 882 rounds were interrupted, and the failure rate was 1.47%. On average, every three magazines would have problems. Therefore, the design of the internal air blowing structure was not adopted by China. When the strong wind of 10 meters per second contains 0.2 mm dust environment, the 95 rifle can carry out normal shooting, but the American M-4 has become a half. Disabled.
Especially in the Yellow River water test, none of the European rifles can withstand the Yellow River water test. Only Maozi’s AK rifle can fight for a while, but 95 rifles in the overall data surpass AK. Therefore, many people think that China's individual weapon (yes, 95 rifle) is not beautiful enough in design and outstanding performance, but it is the most suitable for China's national conditions. China's weapons have inherited the characteristics of Russian weapons that are simple, cheap, solid and resistant.
In 2017, the Philippines imported a batch of Type 97 rifles (the foreign trade version of the 95 rifle) from China. Why did the Philippines choose Type 97 instead of Western weapons? In fact, China exclusively produces foreign weapons for export, but the Philippines does not want Chinese-made Western weapons but chose Chinese-made Chinese weapons? It is because the reliability of the 95 rifle is better than that of European and American weapons. After all, in the Philippines, where the environment in the tropics and the poorly qualified personnel are poor, it is very difficult for them to properly maintain the guns.
