Why are tanks called tanks?

At the beginning of the invention, the water tank was called the water tank, which was determined by its shape. Why is it called a tank now? Because the literal translation of English is English, and it is tank, and its transliteration is tank. So it has been handed down, and people call it a tank.

In the early days of the war, when tanks first appeared, they could be said to be big killers and invincible on the battlefield. It should have appeared during World War I. As soon as this thing appeared, it caused a very big reversal of the battlefield situation. It can be said that this tank can withstand the attacks of 100 and 1000, because it is not afraid of holsters, whether bullets or shells. Generally speaking,

At present, tanks are not particularly high-end weapons. Basically all countries have it. It's nothing more than a question of mode. Some countries may have advanced tank technology, which is very good in both power and attack and defense. And some countries have no manufacturing capacity, so they buy retired tanks from other countries, but in a word, they all have them. Then people invented a special armor-piercing projectile according to the characteristics of tanks, which has strong penetration and can be used directly.

The appearance of a new type of weapon in war often brings great lethality, and many people are killed, but the war is cruel. War is an activity that has to be carried out. Even if you don't take the initiative to invade others, others will invade you for your own benefit when you are not strong enough. If you can't have strong power, you can't defend your own interests and your country, so strong military power is still very useful.
