In real-time strategy games, the role of a tank unit is to provide a health buffer for weaker ranged classes. Frequently maneuvering or other tactics are used by the tank to make themselves the most tempting or highest-priority target of enemy attacks, thereby diverting enemies away from their allies. Many basic strategies in games such as "StarCraft" and "Warcraft III" revolve around learning to micro-manage units so they attack tank units first and that the tanks do not continually attack units.
