Tanks are really big vehicles that can drive over pretty much anything. They have a bunch of really powerful guns and are used for fighting in wars.
The tanks that were made after the cold war are really fancy and have a lot of cool features. For example, they have better armor to protect the people inside and they are also faster and more maneuverable. They also have computer systems that help the person driving the tank aim and shoot better.
These newer tanks are also designed to be able to shoot different types of ammunition that can do different things. Some of the ammunition explodes when it hits the ground and creates a big shockwave that can knock down buildings. Other ammunition is made to pierce really thick armor on other tanks.
Overall, these post-cold war tanks are really cool and powerful machines that can help protect people in war.
