Recently, the organization of the Qiqihar Military Sub district in Heilongjiang Province led a militia detachment to conduct comprehensive and multi course practical training in the extreme cold of minus 20 degrees Celsius. The winter in Qiqihar is long, with the lowest temperature reaching minus 30 degrees Celsius. Conducting winter adaptability training is an important way to comprehensively enhance the combat effectiveness of the militia. ”The leader of the military division introduced. With the command of the commander, the participating teams gathered in the designated area using a combination of motorized maneuvering and foot marching. Drivers use anti-skid techniques to deal with the risk of skidding and drive the vehicle carefully and cautiously. During the march on foot, the trainees carried their equipment and braved the wind and snow to complete the forced army. The white breath they exhaled instantly condensed into frost on their eyebrows. Upon reaching the target area, each militia unit carried out specialized training according to the plan. The road repair team operates engineering machinery to quickly remove snow obstacles and lay temporary passages on frozen roads, solving the problem of frozen soil operations under severe cold conditions; The equipment maintenance team conducts on-site inspections and repairs of simulated low-temperature faults in machinery, and practices emergency repair skills for common problems such as battery depletion and oil circuit icing; The medical rescue team braved the cold wind and carried out casualty search and rescue, hemostasis and bandaging, low-temperature frostbite treatment, and transportation and evacuation training in the snow... The trainees were covered in frost and their hands were red from the cold. The air defense team heard the order and quickly activated firepower equipment to carry out precise strikes, successfully intercepting the incoming target. Subsequently, the transport type unmanned aerial vehicle loaded materials and accurately flew to designated areas in complex snowy airspace to complete delivery, testing the rapid support capability in cold region operations. During the training, participants recorded the endurance time, signal stability, and other data of the drone in low-temperature environments one by one, accumulating first-hand information for subsequent training.
