An example of old styles of armor

Armor is coverings or clothing that people wear to try and not get hurt when fighting, such as in a war. In history, armor is usually made of the strongest material humans know how to make. Early armor was leather, then later metals were used. Some modern armor, like bullet-proof vests, are made from plastics that don't stretch or break very much woven into a cloth and used in layers.

Armor has also been used to protect war animals such as dogs and elephants.

Armor put on vehicles is usually made of metal and can include one layer over another with open spaces in between (spaced armor) or multiple layers of metal, ceramics (hard clay), and other materials. Another type of armor is blocks of explosives that explode when another explosion goes off near it. This explosive armor protects by pushing against the other explosion.

Vehicle armor is often tilted to increase the amount of armor that must be shot through to get inside.
