Tank is one of the main weapons in modern land combat. The tracked armored combat vehicle with direct fire, cross-country capability and armored protection is the only one of the land weapons that is more important than wheeled armored vehicle. It is mainly used to fight against the other tank or other armored vehicles, and can also suppress and eliminate anti tank weapons, destroy fortifications and annihilate enemy land forces.
In fact, tanks are also land weapons with the most natural enemies. Even some tank manufacturers also develop anti tank weapons. Anti tank has become an important capability of the army of all countries. Although the tank is developing, the development speed of the tank itself can not catch up with the development speed of the anti tank weapon, and the tank will fall into the two paradox problems that the protection and cross-country ability can not be both. Unless new lightweight protective materials are developed to improve armor, tanks will be in a very dangerous position in future wars.
