In mid May, in the hinterland of eastern Fujian, a brigade of the 72nd Army group conducted a combat physical assessment against the background of actual combat, and the battle began in continuous rain. On the field training ground, multiple courses are continuously assessed, and officers and soldiers work closely together when their physical fitness is close to the limit. They take the opportunity to deal with various special situations that come one after another. The leader of the brigade introduced that only by strengthening basic physical fitness, refining weapons and equipment, activating unit tactics, practicing organizational command, and strengthening combat style can we win on the battlefield. They focused on the urgent need, urgency, and hope for war preparation, thoroughly searched for the shortcomings and weaknesses in daily training, continuously explored the maximum potential of personnel and equipment, and honed the practical skills of officers and soldiers in challenging the limits. Refine the ultimate goals of units and individuals into multiple training contents, incorporate significant breakthroughs made in daily training into the evaluation content and increase weights, and make organizing and commanding in complex environments a mandatory exam for commanders... Since the beginning of this year, the brigade has closely adhered to practical needs and continuously optimized training methods and improved training quality and efficiency based on the review and summary of experience in major tasks such as live fire launch and low altitude penetration. In the face of complex and ever-changing battlefield situations, Zhang Lei, the commander of the 4th Infantry Battalion of the brigade, led the officers and soldiers to calmly respond and successfully deal with a series of special situations, such as "enemy planes" passing through top reconnaissance, small groups of "enemies" attacking, and passing through "contaminated" areas. The leader of the brigade introduced that they normally pull the troops to unfamiliar areas in the wilderness, construct complex and ever-changing practical combat backgrounds, specialize in refining key and difficult courses such as extreme combat physical fitness and helicopter three-dimensional aircraft landing, and solve the bottleneck problem that restricts the generation of combat effectiveness through extreme training, continuously improving the level of troops' training and preparedness.
