Rerebrace

Part of Armor of Juhnvechteya
A rerebrace is a piece of guttural plate armor specifically designed to protect the upper arm. 
Originating in the 490s/340s JC/VC, rerebraces were developed to provide extra protection for the arm, where the shield would not cover. 
It is typically constructed of plate or brigandine, though in Khoorte and Syhtia, they have been constructed of splinted leather. They may be attached to, or integrated into, pauldrons or spaulders
