ROC

公式説明（原文）At Greycat, we understand that mining isn't a one-size-fits-all operation, so we designed the ROC to be as hard-working and versatile as the miners who use it. Small enough to access hard-to-reach ore deposits, but with enough power to get through the tough jobs, the ROC perfectly complements any mining enterprise. It's perfectly at home supporting full-scale operations, and a first-rate starter vehicle for fledgling diggers. Whatever the task, with Greycat, you have the right tool for the job.
