Farts and Darts
Military field grade officers have decorations on the brims of their dress hats. All other services routinely have oak leaves in gold or silver. The U.S. Air Force has clouds and lightning bolts on the brims of their hats. They are referred to as "farts (clouds) and darts (lightning bolts)".
