Orc Military:
Big'urs- Big'urs are the heavy infantry of Orc armies. They are equipped with the best weapons, and as much armor as they can scavenge. They are, as the name implies bigger than most orcs, meaning that they are older and more experienced. They are also the leaders of regular "units" of orcs in battle. The normal orcs often call them boss when talking to them, mainly so they don't get their heads beat in by the Big'ur. Big'urs use more than just conventional weapons. They also use their teeth, often coated with metal, and their massive bulk smashing into enemies.
Arrers- Arrers are the specialized archers of the orcs. Like all orcs, Arrers are trained in war as soon as they can walk. The Arrers however are more highly skilled when it comes to ranged warfare than the other orcs. They are regarded with suspiscion by the others, often made fun of for "not wannin' tah get inna good scrum, an' lookin' funny." Arrers often dress differently than other orcs, but they are effective archers, while not very accurate, (they are orcs after all), they manage to lay down a withering hail of arrows.
Shamans- Shamans are the most religious of the orcs. They are never dressed in anything more than a loincloth, and have tatoos all over their body. These tatoos have mystical signifigance, and the orcs believe it protects them in battle as well as helps them commune with their god. This is slightly true, as once a week and/or before battle, the Shamans cover their tatoos with a hallucinogenic drug, causing them to see visions and feel no pain. They do seem to be in their god's favour however, because if the need is great, they do sometimes get magic from their patron.
Stunties- Stunties are used as cannon fodder. They are basically orcs with birth defects, causing them to grow at a much slower rate. They do have a slightly larger intellect than other orcs. Stunties are the size of human children for the most part, and when they are not fighting in a battle, are in their own seperate area of the orc camp. They do much of the orc "inventin'," and are an orc sub-culture. They have their own Big'urs, Arrers, and Shamans, although they are less effective than their larger orcs brethren.
