In the game worlds of Warhammer Fantasy and Warhammer 40,000, Goblins (or Gretchin or Grotz in Warhammer 40K) are basically smaller Goblinoids (Orkoids), which are more cowardly than Orcs and are usually used as living shields, to clear mine fields, are stepped on to get through difficult terrain, and sometimes even as emergency rations. They are quite low in Goblinoid society (the lowest being Snotlings) and are often used for the dirtiest jobs like scavenging and playing football with when the Orcs get bored.
