In StarCraft, the Terran unit that can deploy a Spider Mine is the Vulture.
The Vulture is a fast Terran hover vehicle equipped with a long-range fragmentation grenade launcher. Its special ability allows it to place Spider Mines, hidden explosives that trigger when an enemy approaches. Mines are especially useful for protecting expansions, controlling routes, and punishing large movements across open ground.
The Vulture is a ground vehicle, unlike the Goliath, which uses anti-air and anti-ground missiles, and the Siege Tank, which can switch into long-range artillery mode. Spider Mines are associated with the classic Vulture in the original StarCraft and Brood War, while later games changed how Terran mine technology is represented.
