Chainmail is a type of armor made from interlinked metal rings. It was commonly used in the Middle Ages to protect soldiers during battles. The rings are usually made of steel or iron and are woven together to create a flexible yet strong protective layer. This armor was effective against slashing attacks from swords and other weapons. While it provided good protection, it was not as effective against blunt force or piercing attacks. Chainmail was often worn over padded garments for added comfort and protection, making it a popular choice among knights and soldiers of the time.
