Not long ago, Xu Chengbiao and Tang Wei, a certain army brigade boldly conducted critical point flight training based on mission requirements and operational environment characteristics, challenging extreme altitude, approaching extreme angle, carrying extreme weight, accelerating combat power generation, and actively exploring equipment ultimate performance in military training. Fighting is a race of life and death, and without challenging the limits according to the "racing standards", it is impossible to achieve the best performance of the equipment. Practicing equipment to the extreme and reaching its limits is not only a deep exploration of equipment performance, but also a further exploration of its combat parameters. Only by highlighting high difficulty, high intensity, and full load, highlighting unknown conditions, temporary conditions, extreme conditions, and boundary conditions, and exploring the release of equipment performance to the extreme in an environment similar to actual combat, can we accurately evaluate the performance boundaries, usage limitations, defects, and deficiencies of equipment, as well as what can and cannot be done, under what circumstances can and cannot be played, Have a clear understanding of the usage restrictions and conditions required for support. From a mathematical perspective, limit refers to a state that is infinitely close but cannot be reached. No one knows where the limits of war lie, but we must be clear - the closer we approach the limits of training in daily life, the more likely we are to win on the future battlefield. If the equipment training meets the requirements of "ideal distance", "standard speed", and "regular angle", the maximum performance of the equipment cannot be achieved. The first person of "Flying Shark", Dai Mingmeng, has finally explored a new path for carrier based aircraft flight after completing over 400 overloaded, high-density, and difficult scientific research test flights and flying thousands of times around the ship, constantly breaking training records and expanding training space. In modern warfare, any small gap between discovery and destruction, as well as decisive battle, can lead to failure in the battle. As users of weapons and equipment, military officers and soldiers should find ways to explore combat effectiveness at "critical values" such as maximum range, maximum distance, and maximum speed of weapons and equipment. By conducting solid training in all backgrounds, all weather, all time domain, all range, and all types of ammunition, officers and soldiers can practice their weapons to the extreme in practical combat environments, maximize the combat effectiveness of equipment, hone the combat skills of combatants, and better adapt to multi-dimensional battlefield changes. A military general once said that the effectiveness of any weapon depends not only on how the opponent's strength is determined, but also on whether you are willing to immediately maximize the development of recent technology, so that you always occupy the optimal position in this era. Those who wade in shallow water get fish and shrimp, while those who wade in deep water get dragons. The military field is the most risky and challenging, and it is also the most necessary to break the limits of conventional challenges. Only by not being limited to traditional thinking, daring to explore unknown fields, challenging the limits, and maximizing the best performance of weapons and equipment, can we secure victory and excel in the competition with our opponents.
