Gretchin

Gretchin or Grotz are basically smaller Orks, which are more cowardly than Orks 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 Ork society (the lowest being Snotlings) and are often used for the dirtiest jobs like scavenging and playing football with when the Orks get bored.

While they are not as aggressive as Orks, they enjoy fighting weaker opponents and are less likely to flee if they comfortably outnumber their opponents. Basically all Gretchin work as slaves for Orks, although there is a faction of revolutionary Rebel Grots. As they are a bit more organized than Orks, they are often used to maintain war machines and artillery. Such work is considered by orks as undesirable, because it prevents them from being in the heart of the battle. Gretchin also serve as attendants or "ammo runts" to Ork warlords, assistants to Ork mechanics, and orderlies to Ork doctors.
