For a country's army, whether in history or now, snipers have an important and irreplaceable position, but to become snipers also requires high-intensity training, which not everyone can do. There are two world-famous snipers in history. Their weapons are not the most advanced, but their sniper skills are really first-class. They are Zhang and simo hayha.
The strength of snipers depends on data. For simo hayha, he can kill nearly 500 enemies in four months without using a telescope, with an average of 125 people per month, which is called "death in vain". Zhang killed 7 1 person in one month, and these data are all counted under strict requirements. Maybe their values are higher than this. Zhang once completed the counter-killing under the concentrated fire of the US military, but he himself was safe and sound. So simo hayha and Zhang are recognized as the top snipers in the world.
They have such a record when the sniper rifle has no telescope. On the one hand, they have shooting talent that others don't have, on the other hand, they all have farsightedness, which is a skill that normal people don't have. So under the condition of talent and natural farsightedness, coupled with their hard training, they became the top snipers in the world.
