Since the implementation of the new military officers' policy and system reform of daring to challenge "professional mismatch", the professional counterpart rate and post adaptation rate of military cadres have significantly improved. However, after a small number of military academy graduates were assigned to the grass-roots units, the phenomenon that their majors were not appropriate still existed. Faced with this situation, the new platoon leader can only successfully obtain the "work license" for grass-roots posts by maintaining a clear mind, a studious state and a diligent attitude, and daring to challenge the "professional mismatch". For individual cadres, it is actually a dynamic process that the specialty is not matched. In the long run, with the promotion and job changes of the current professional counterparts, the cadres are likely to be adjusted to the positions of professional counterparts; From the perspective of practical needs, even if they are assigned to professional counterparts, due to the accelerated updating of knowledge and a long time, it is difficult to meet the needs of reform, building a strong military and modern warfare. Qian Weichang, the father of modern Chinese mechanics, was admitted to the Department of History of Tsinghua University with full marks for both Chinese and history. After the September 18th Incident, Qian Weichang resolutely decided to transfer to the Department of Physics to learn how to build aircraft cannons to revitalize China's military. He has a famous saying: "I have no major, and the needs of the motherland are my major." In the face of the reality of "professional incompatibility", the new platoon leader should maintain a zero point mentality. As long as it is organizational arrangements, national and military needs, the major can be transferred, the position can be changed, and the platoon leader should be loyal to the country without complaint or regret. Diplomas can only represent the past, and learning determines the future. The new platoon leader entered the camp gate from the school gate, moved from the playground to the battlefield, and changed from a student to a commander, facing many new challenges. If you are assigned to a position with wrong profession, you will face more and more difficult challenges. In this case, the new platoon leader should be self-motivated, adhere to what he/she does and what he/she lacks, focus on the weak points, pay close attention to learning, and strive to make his/her talent continuously grow; We should take the initiative to put aside our airs, take the grassroots officers and soldiers as our teachers, ask questions if we don't understand, learn not to learn, and practice if we don't, and learn professional skills as soon as possible; We should pay attention to practice, and strive to transform the learning achievements into ideas for planning work and the ability to solve problems. Only in this way can the improvement of learning ability promote the enhancement of professional ability, and wherever you go, it will be "sweet cake". The main road is simple and practical. The biggest difference between professional and amateur lies in their attitude towards work. Wang Zhongxin, the winner of the "August 1 Medal", had only a junior high school diploma when he joined the army. Facing various challenges such as equipment updating and post adjustment, he chose to rise to the challenge and finally mastered the professional skills of 19 missile posts. Facts have proved that nothing is difficult if you work hard. Students learn only one major in military schools, but are often assigned to more than one major in the army. Only when the new platoon leader takes his post as the battle position, actively adapts, runs hard and speeds up his growth, can he be loud and write a new wonderful chapter for his military career no matter what post he changes.
