Recently, officers and soldiers of a border defense brigade in the Northern Theater Command, Heihe Hao Eighth Company, discovered that border facilities in their jurisdiction were submerged by rivers while on duty. If they were not salvaged in time, losses would be caused. However, more than 20 officers and soldiers were not injured at all. Without hesitation, they jumped into the icy water to salvage, and dragged the border facilities to a safe area.

This scene made countless netizens cry out distressed, wondering how the officers and soldiers kept warm in the extremely cold weather. It is understood that in order to prevent border guards and soldiers from getting cold, the motherland has finally completed the transformation from traditional "four-skin" clothing to new cold-proof clothing. At the same time, we actively draw on the experience of foreign armies in cold protection to develop 11 new categories of underwear, fleece vests, fleece jackets, cotton coats, winter training uniforms, imitation wool winter uniforms, cotton coats, cold-proof shoes, outer boots, and internal and external gloves for troops in plateau and cold areas. variety. According to reports, the design of our army's new cold-proof clothing also draws on the US military's ECWCS system. It has as many as seven layers of insulation. It is lightweight, waterproof and breathable. It does not feel restrictive when worn, and it can last long on the snow at minus 30 degrees Celsius. You won't feel cold even when lying on your stomach, and can adapt to various ambient temperatures. In addition, more than 20 kinds of clothing and equipment have been distributed to meet the needs of various combat training and extreme environment duty tasks.

One full charge can keep them warm for 8 to 12 hours. In addition, there is a multi-functional tactical cloak that can automatically adjust the temperature and can be used as a sleeping bag or tied to a tree as a hammock. ? Although the physical strength of border guards is different from ordinary people, no matter how powerful they are, they are still made of flesh and blood. Therefore, the border defense troops were stationed in the border defense areas and built border defense towers, which contained hot water and heat preservation rooms needed by border defense officers and soldiers. After the border guards are on duty, they will go back to the small room to take a hot bath and drink hot water. Heihe, as the earliest open city along the border in China, is located in the eighth coldest zone in China. The freezing period lasts for more than 160 days and the ice layer is nearly 1 meter thick. The officers and soldiers stationed there at the "Heihe Hao Eighth Company" post have nearly 100,000 soldiers stationed there every year. For half a year, they have to stand guard on the river in temperatures of more than minus 40 degrees Celsius for 6 to 8 hours. They are not afraid of hardships and strictly guard the country's borders. Although the ice is cold, it cannot freeze the passion of the border guards.
