Chain Barding Armor is the further upgrade of this technology.
- A team containing Bulgarians: Researching Scale Barding Armor is 80% faster.
Barding was armor placed on horses. Scale barding armor was made of layers of rounded metal scales that overlapped each other in a cascade. This partially protected the horse from both arrows and hand weapons. A blow against the armor was partially deflected, and the layers of scales absorbed much of the energy of the blow.
