A conflict took place on the planet of Myrkr in 3963 BBY, during the Mandalorian Wars, pitting the Galactic Republic against the Mandalorian Neo-Crusaders. The Republic Military and the Mandalorians engaged in combat, resulting in around 2,000 losses for the Republic in a single night. On the other hand, the Republic forces were able to recover Neo-Crusader shock armor and started a research project on it.
