A tank or meat shield is a character class commonly seen in co-op video games such as real-time strategy games, role-playing games, fighting games, multiplayer online battle arenas and MUDs. Tank characters distract enemy attention and attacks toward themselves in order to provide protection or decoy for teammates. Since this role often requires them to endure concentrated enemy attacks and often suffer large amounts of damage, they rely on a high health pool or armor level, healing support by friendly healers, evasiveness and misdirection, or self-regeneration while simultaneously sacrificing their own damage.
