兵馬俑
Six groups of armour have been identified in the Terracotta Army corresponding to rank and military division. Some soldiers are outfitted with little to no armour at all, cavalrymen with armour that covered the chest, armed infantry with armour covering the torso and shoulders, low-ranking officers with armour using large lamellae, middle-ranking officers with shorter armour covering the torso and waist or just the breast, but with decorations such as ribbons, and generals with a distinctive coat showing torso armour and ribbons to signify their status. None of the terracotta soldiers have been found wearing a helmet or holding a shield. However, this may be because the terracotta soldiers are simulating a funerary procession for their ruler, and according to protocol, subordinates had to remove their helmets when appearing before the emperor. Helmets have been found in other excavated pits near the terracotta soldiers. Furthermore, another explanation for both the lack of both weapons and helmets for the terracotta army is that most of the functional, useable equipment made for the terracotta army were believed to have been looted during the rebellion against the Qin Dynasty.
