[Source] Calo Nord's battle armor was a customized battle armor based on modified Mandalorian design. It provided basic protection against ballistic and melee attack, and also offered resistance against cold, fire and sonic attacks. Originally worn by Calo Nord, the battle armor was appropriated by Revan and his companions after they killed Nord. The armor was the only one of its kind, because the designer was killed in order to ensure that the battle armor would be unique.
