I want to ask a question, what is the difference between ancient wars and modern wars?

Needless to say, the upgrading of equipment. In ancient wars, formation was the most important. Once the formation is laid, it will not be easily changed, otherwise it will be easy for the enemy to seize the gap and break it in one fell swoop. Although modern warfare also pays attention to formation, modern formation is generally a small unit formation based on firepower group, and it can be changed at any time to deal with different situations during the attack, which is more flexible than in the past.

Another major change is urban warfare. In the past, urban warfare was a hand-to-hand combat between the two sides on the streets of the city. This is just narrowing down the strategies of field operations and putting them on the street. For the defenders, basically as long as the city wall is broken, they don't want to turn over (although it's not an example of not beating out the enemy who enters the city). Modern urban warfare mainly focuses on clearing streets and +CQB. The participating troops should carefully scout or bomb every building on the attack route, or they will have to let the infantry enter the house to fight the enemy (the ancient army can't open it indoors, even the smallest three-man and three-talented array can't be released, so the ancient army basically doesn't enter the house in the urban war), so the defending city side has a great chance to defeat the siege party entering the city.

As for informationization and mechanization, I won't talk about it. These things were basically immortal means in ancient times.
