Jaing (aka Jaig) eyes... it's a battle honor, worn as a symbol of valor on the battlefield, usually earned by saving the lives of commrades or by single handedly turning the tide of a battle... the backstory for why my mando wears jaing eyes is that during a battle against the vong, he stayed behind, with 3 other commandos while the rest of the force extracted under the umbrella of close air support that he was coordinating from the ground. This would be about halfway through the vong wars after the mandalorian protectors switched sides.
