Black Orc
The Black Orcs are a sub-faction of the Orcs and Goblins in Warhammer Fantasy, and are quite possibly the hardest front line unit on the north side of Warriors the Chaos. Clad in what amounts to plates of kettle metal, brandishing various weapons of the beating, slashing and crunching variety and with a mean streak at least a few miles wide, Black Orcs are the classic elite unit of the Orcs and Goblins faction, and is comparable to Empire Greatswords, Tomb Guard and Temple Guard as melee-units made for krumpin' without being Blood Dragon-like expensive and killy.
Black Orcs are named after their dark green skin and their black armour, which stands in starch contrast to the usually ragtag look of other Orc units, which is mostly painted by shit and blood. This stems from the very first unit of Black Orcs, which was originally slaves who were almost worked to death and tortured by Chaos Dwarf slavers. Being constantly beat and threathened with death without a fight, the Orcs began to band together to plan out elaborate escape plans which included copious amounts of dead Chaos Jews. After the riot, the Orcs broke free and joined nearby Orc tribes, but had difficulties fitting in because of their diciplined way of fighting and abilities to work as a team. As such, Black Orcs are more like wandering bands of elite warriors who few Orcs particularly like for their un-Orcy ways, but won't mind when they get into a scrap and show how absolutely hardcore they actually are.
On the battlefield, Black Orcs are entirely unlike the regular Orc mobs; they are highly diciplined, well armed with multiple types of weapons at hand and armoured from toe to teef. When a Black Orc unit marches, it's in almost unison, with no bickering and or grumpling going on in the regiment. Where a regular Orc is an opportunistic and barbaric berzerker, Black Orcs are deciplined, professional soldiers.
