In order to meet the increasingly stringent requirements of urban operations, the corner shooting system is optimized. This paper points out the defects of the system in the operational application, puts forward the optimization idea based on the actual combat application, and designs the specific improvement and optimization concept, which is optimized and upgraded comprehensively from the improvement of fire attack, the integration of auxiliary functions, the embedding of information modules and other dimensions. The results show that the optimized corner shooting system can better meet the needs of future urban combat, continuously release its powerful combat effectiveness, and lay a solid foundation for the victory of combat.
