The Skirmish in the Ulker asteroid belt was a minor engagement of the Cruentusian War. It occurred when a raiding force of the Taung Confederacy, making advancements into the system of the Sinyan Imperium, sent a small force into the local Ulker asteroid belt to harass Sinyan supply lines and facilities. However, owing to supposedly superior tactics under the command of the Jev Strayker, the Sinyans were able to repel them.
