According to TES lore, every Redguard must brave a Dwemer ruin before embarking on a military career. From here I have made it that a Redguard must bring back dwemer scrap metal as proof from which they make their armor from = Dwarven armor.
Whereas most Redguard of Hammerfell wear light clothing due to the heat, those in the military have a full set of Dwarven armor to protect them during a full-on melee combat situation. Something brought in from the days when fighting against and driving out the Orsmer.
