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.

The Kangaroo is Oceanyka's only natively designed high performance piston fighter. Neither the government, nor the Japanese, nor the rebels expected much from this humble nation, but they were proven wrong. Much like its namesake, the Kangaroo always stood its ground, always accepted a challenge, and always promised a good beating. When dogfighting with this aircraft, if the enemy has an Air Superiority advantage, reduce it by 2 but never below 0.
