Grunts are the basic warriors of the Horde and the orcish clans. They are typically equipped with mighty axes and battle-worn armor.
Grunts appeared as units on the orc or Horde side in Warcraft, Warcraft II and Warcraft III. They are the classic counterpart to human footmen but are stronger than them in Warcraft III. They do, however, cost much more. In all the strategy games they are voiced by Bill Roper.
