Judging from the rank, Zhang and Yin Zhuo are the rank of major general and the rank of senior colonel, which is one rank apart; According to the arms, Zhang and Yin Zhuo belong to the navy, and he belongs to. Although the military development makes the tactical equipment between different arms gradually close, there are still some differences, which is also an important factor in the confusion of grades. Then there is actual combat experience. Zhang and Yin Zhuo are older, so they are forbidden to talk in actual combat. Although they are not direct campaign commanders, their experience on the battlefield is irreplaceable. Du Wenlong and Fang Bing have mostly experienced drills and drills, but they have no actual combat experience. This is very important. No matter how good your words and analysis are, it is an armchair strategist if they can't fight on the battlefield. Therefore, I prefer Zhang and Yin Zhuo, who are older. No matter how many hours you study, you can't mention the experience of war. One more thing, the older generation of military experts may be more stable, and they are well-behaved in dealing with problems, while the new generation of military experts are bloody and masculine, and have the characteristics of novelty and boldness in dealing with problems. This is what people often say about the "younger generation". After all, China's modern military forces suddenly made great strides, and its strength naturally stood.
