If it's a game, I don't have to watch what I said. If it is history, I think I can answer you.
The main arms of ancient western wars were divided into Roman series and British series.
The main difference is the equipment of cavalry and infantry.
Roman series
The cavalry of Roman series is mainly light cavalry, with few armour, spears and long knives, and it is mainly based on speed and individual combat.
The most distinctive features of infantry are trident soldiers and double sword soldiers. Trident soldiers originated from Rome's worship of Poseidon, while double sword soldiers were the unique arms of Rome's worship of attack and gladiator.
In addition, the Romans' bows and arrows were not very powerful, because when the Roman Empire was established, they fought many wars with Persia, and Persia was defeated every time. Therefore, the Romans believed that bows and arrows were used by the weak to defend themselves, not to attack, so they were less equipped in the army.
There are also shield soldiers, including gun shields and sword shields. The Roman shield is distinctive, with two guns on the front, which can be used to produce lethality when the shield hits.
In the Roman series, guns are the bane of cavalry, while bows are of little use. Sneaking is ok. Cavalry can effectively attack double-sword soldiers by taking advantage of speed, but the advantage is much smaller when dealing with shield soldiers, and the proportion of casualties will not be too large.
England series
The most representative British series are long swordsmen and heavy cavalry.
Long swordsmen are characterized by great lethality, because the handle of two-handed swords is long, suitable for hard training, but not flexible enough. This also shows that the British don't like sneak attacks. Everything is open. I'm telling you, I'm going to hit you, not to prevent you from defending, but to prevent you from defending.
Heavy cavalry is characterized by super heavy armor, long "toilet war spear" and a row of knives in front of the horse neck. The tactic is to open a row, start from 1000 meters away, accelerate with such a long distance, and finally hit the opponent's morale with super impact and shock.
There is no bow in the British department, only crossbows, mainly crossbows. Tactics are also open platoon. The difference between bow and crossbow is that one is curved and the other is straight. The best position of the bow is 40 degrees, and the target is uncertain. The best position of the crossbow is flat shooting, and the hit is always in the first row of the queue.
England series also has spearmen and sword and shield soldiers, and one is axe and shield soldiers.
In the English series, there are a large number of spearmen and crossbowmen, but almost no arms are opponents of heavy cavalry. Generally speaking, 1000 heavy cavalry can beat 50,000 infantry with little casualties as long as there is enough acceleration distance. But this is also the shortcoming of heavy cavalry. The ability to prevent sneak attack is very weak. A heavy cavalry without impact is a waste, and it is difficult to move.
Even the spearmen, when they haven't reached the absolute advantage in number, can't resist the impact and will be wiped out.
Finally, the number of heavy cavalry is small, mainly because the arms need good physical strength, excellent driving skills and the best horses, so it is quite extravagant for such an island country.
