The "Iron and Steel Battalion" continued to write a new chapter of winning the war - the second mobile team of the fourth mobile detachment of the Sichuan Armed Police Corps earnestly studied, publicized and implemented the spirit of the 20th CPC National Congress. In the early winter, a year-end military training assessment was held in a place on the plateau as scheduled. Suddenly, the sky began to snow heavily, and the temperature dropped suddenly, as if to test the officers and soldiers of the Mobile Second Brigade of the Fourth Mobile Detachment of the Sichuan Armed Police Corps who participated in the assessment. "In the Huaihai Campaign, our ancestors had outstanding achievements, and the predecessor of the brigade was awarded the honorary title of 'Iron and Steel Camp'. Today, we 'descendants of iron and steel' should hold high the banner of heroes and fight bravely for the first place!" After a brief mobilization, the brigade instructor Jia Chunbin, who served as the military commander, led the officers and soldiers to walk over obstacles, climb tactics, and play live ammunition on the muddy assessment field... All of them overcame the bad weather, and their morale was high and they fought bravely, which impressed the superior assessment team deeply. Squadron leader Bian Ba Jinmei relapsed his old leg injury in the assessment, gritted his teeth until the end, and led the squadron to achieve excellent results; Corporal Luo Xu insisted on taking part in the assessment just after his bad cold got better, and finally achieved excellent results; Sergeant Ma Zhifang just returned from vacation. He could not adapt to the adjustment and completed the assessment with excellent results... In the snow, the flag of the "Iron and Steel Camp" was flying. The reference officers and soldiers of the brigade braved the severe cold and won the first place among the reference units of the detachment with indomitable fighting spirit. This assessment is a microcosm of the team's officers and soldiers learning, publicizing and implementing the spirit of the 20th National Congress of the Communist Party of China. In recent days, they have organized and carried out the theme practice activity of "learning the spirit of the Twentieth National Congress of the Communist Party of China and being a loyal defender of the Party" in combination with their experience in the reform and reconstruction of the military and practical training in recent years, using various forms such as leading cadres to learn, special study and discussion, and story meetings to strengthen the military, so as to further strengthen the faith of officers and soldiers in listening to the command of the Party and striving to strengthen the military. "On the new journey, can we withstand all kinds of challenges and tests?" During the study and discussion, Kong Taotao, the Second Staff Sergeant, combined with the important statement of "comprehensively strengthening the Party building of the people's army and ensuring that the guns always listen to the Party's command" put forward at the 20th National Congress of the Communist Party of China, told an emotional story. At that time, the unit received the order to transfer to the remote western Sichuan Plateau. This made Kong Taotao a little nervous: a year ago, his wife quit her job in Youwu, his hometown, and came to settle down. The couple finally ended their life as "Cowherd and Weaver Girl", and the child was only three months old. "To be absolutely loyal to the Party is to stand up at the critical moment and be willing to go out in times of crisis. The glorious banner of the Iron and Steel Camp cannot allow me to retreat and hesitate." Thinking of this, he made a firm choice and persuaded his wife to follow him to the plateau. Kong Taotao's mental journey has aroused strong resonance among officers and soldiers. In this reform examination, all the officers and soldiers of the brigade firmly and consciously supported, obeyed and committed to the reform. At the command of the organization, they set out with their backpacks, and no one bargained. They all said that they would resolutely follow the command of the CPC Central Committee, the Central Military Commission and President Xi Jinping, be absolutely loyal, absolutely pure and absolutely reliable, and ensure that the guns always follow the command of the Party. "The 20th National Congress of the Communist Party of China emphasized strengthening the cultivation of fighting spirit." At the strong military story meeting, platoon leader Wang Yukuan felt deeply about this. At the military parade marking the 70th anniversary of the founding of New China
