A mineral stripper was a massive terran-designed vehicle in use by the Guild Wars, designed to process minerals. It was as long as a 30 story tall office tower and could move on massive treads. Smaller vehicles could actually take cover behind the treads. As a stripper crawled, it could take in a 50-foot wide strip of ground, including minerals. On Turaxis II, a number of mineral strippers were provided by Raffin Brothers Mining.
