China has been using recurve bow since the Han Dynasty. According to ancient records, the ancient Egyptian compound bow can penetrate 30-75cm copper plate, the Assyrian compound bow has a range of 600m+, and the Roman compound bow has a range of 650m m. The most famous Turkish flying bow, 20 grams of light arrow, has a flight record of 800 meters. The range of the British longbow is indeed between 150 and 180 meters. Physical theory tells us that the angle of 45 degrees is the farthest, and the maximum range of elevation angle is also the maximum effective range, which is different because of gravitational potential energy.

The ancients in China were flat mirrors. Is it a vertical bow or a flat hand on your chest? The bow on the chest is because the compound bow in ancient China is big enough to shoot at the enemy who can aim at the chest, so it can provide the effective range as much as the 45-degree angle shooting when the British longbow is launched (correct, in archery, the front archery is more accurate in the forward direction). It's embarrassing to have one hand flat on your chest. The restored Song San Palace bed is 400 meters away from the hotel. During the Spring and Autumn Period and the Warring States Period, Qin Guofan: Thirty villages shot about 189 meters, four guns shot 252 meters, and so on. The range of ten stone cymbals can reach more than 600 meters. It can be seen that the range of cockroaches in ancient China has been far away, and the pursuit of range is also decreasing, mainly for the pursuit of chest shooting accuracy. Different shooting methods, western movies like to shoot thousands of troops, a feeling of dark and heavy rain volley.

China movies, I still remember the clothes I saw when I was a child. Are close-ups of arrows shot by the general with his sword. Ancient military bows and arrows are very different from modern bows and arrows. In other words, ancient bows were many pounds and arrows were heavy. If the air resistance is excluded, the energy of the arrow when it returns to the same horizontal plane is the same, regardless of the shooting height. Kinetic energy is converted into potential energy, and potential energy returns to kinetic energy. So the lethality is definitely enough. Although air resistance reduces a lot of kinetic energy, it still has power. But I personally think that the working distance of general ejection ranges from 500 meters to more than one kilometer (yes, you remember correctly, bows and arrows can shoot one kilometer as long as one kilometer! Of course, the accuracy is completely ignored). At such a long distance, the ability to penetrate armor may be limited.
