FAAC 'Em Up!
Whoever named the Oceanykan Federation's Federal Army Air Corps (FAAC) clearly knew the value of propaganda. When the Oceanykan Civil War broke out, and particularly when the Japanese invaded, the FAAC became synonymous with rudely expressed defiance. Whenever an aircraft with this rule has below 50% RES, it can reroll a single dice roll of any kind per turn.
Sabre Dance
American Sabre pilots flying over Korea became renowned for their daring against numerically and sometimes qualitatively superior forces: the fearsome MiG series, flown by Soviet "volunteers". They would push their machines to their structural limits if it meant putting an enemy jet on their gunsight, for they needed but a fraction of a second to bring it down with a swift burst. When Dogfighting, the F-86 Sabre's pilot may expend 2d20 of their aircraft's RES to gain +1 Air Superiority for a Short Duration. This ability can be repeated and stacked indefinitely.
