The *Beiwei* Army was an elite force under the direct command of the renowned Southern Song general Yue Fei, celebrated for its shock cavalry tactics. This suit of heavy armor follows the military styling of the Southern Song Dynasty; it is constructed from hot-forged iron lamellae—layered and laced together—and lined with thick cowhide and silk, with iron components treated with a black finish for rust resistance. It features substantial chest and back protection and a skirt with slits to facilitate mounted combat, while the detachable pauldrons and vambraces—paired with an iron helmet and neck guard—provide comprehensive protection from head to knee. The armor’s deep black finish is accented with touches of gold gilding, evoking the formidable and imposing aura of the elite *Beiwei* troops.
