Tank
Most modern tanks most often have four crew members, or three if an auto-loader is installed. These are the:
Historically, crews have varied from just two members to a dozen. For example, pre-World War II French tanks were noted for having a two-man crew, in which the overworked commander had to load and fire the gun in addition to commanding the tank. First World War tanks were developed with immature technologies; in addition to the crew needed to man the multiple guns and machine guns, up to four crewmen were needed to drive the tank: the driver, acting as the vehicle commander and manning the brakes, drove via orders to his gears-men; a co-driver operated the gearbox and throttle; and two gears-men, one on each track, steered by setting one side or the other to idle, allowing the track on the other side to slew the tank to one side.
Crowd control (video gaming)
As in "EverQuest", crowd control can also be provided by having a sufficiently resistant character, such as a Tanker, Scrapper, or Brute archetype character, keep the opponents occupied by "tanking" them. Tankers and Brutes are intended to be much more effective in this role, and it is not unheard of for a Tanker to "tank" upwards of 10 opponents at once and survive. Tankers, Scrappers, and Brutes all have powers that Taunt, which makes this task easier, but changes to the game in Issue 5 limit the number of targets that can be effectively controlled in this fashion, and the overall reduction in character defense makes tanking more dangerous. As of Issue 7, the Mastermind archetype has an inherent power called "Bodyguard" that, under specific circumstances, allows him to redistribute damage taken to his pets. Despite his limited hit points, a Mastermind can act as a "tank" using this power if carefully played.
