Pauldrons
In the grim darkness of the far future, there is only war. Unless you have Imperial power armour, in which case there is also pauldrons. Pauldrons are the sections of armour that cover the shoulders, and are well known for the tendency of artists drawing Warhammer 40k material to make them ridiculously huge. World of Warcraft armour also tends towards oversized shoulder-plates.
It is theorised that position in Imperial society is directly related to how large your pauldrons are, as exemplified by artwork of the Empra himself, who has power armour with pauldrons so massive he cannot see over his own shoulders or raise his arms to more than a forty-five degree angle. Those unfortunate enough not to be equipped with power armour instead use the size of their hats in a similar manner.
