Let's not overlook the whistling wings of the Polish Hussars.
"While the badass weaponry and armor was unquestionably utilitarian, the Winged Hussars also went that extra mile to ensure that they were armor-crappingly terrifying while charging ahead in perfect formation. Their armor was burnished and well-polished so that it gleamed in the sunlight (most Renaissance-era knights preferred black armor because it was more resistant to rust), they wore brightly-colored heraldry, and OH YEAH they also had giant-ass fucking wings strapped onto their backs. These wings, which were made of ostrich or eagle feathers glued onto wooden frames that arched up and over the back, made an insane whistling noise while the Hussars were charging, completely unsettling, terrifying, and overawing the enemy in the brief moments between when they said, "holy shit WTF" and when they had a kebab skewer jammed into their eye sockets at about a hundred and twenty miles per hour. Some of the Hussars also used to up the "wow factor" by stuffing severed heads down the tips of their weapons and charging into battle with a lance-full of heads, which sounds pretty gnarly."
