本文从直瞄武器的Ｌａｎｃｈｅｓｔｅｒ方程出发，通过严格的数学推导分析了优势兵力条件下不同作战方式的作战效果，并且通过对战斗进程的建模分析，论证了几条战术原则的正确性，同时也得出了一些具有战术指导意义的结论。本文还提出了延时支援的概念。 Based on the Lanchester equation of straight sight weapon, this paper analyzes the combat effectiveness of different combat modes under the condition of superior forces through rigorous mathematical derivation, and demonstrates the correctness of several tactical principles through the modeling and analysis of combat process. Come to some conclusions of tactical significance. This article also proposed the concept of delay support.
