Gundabad Army

Bolg is sent by his father Azog to lead forth the armies of Gundabad. There are two types of Gundabad Orcs, the armored soldiers and the Berserkers. The Berserkers have white snow-like skin and are stronger built than their fellow Gundabad Orcs, with long almost ape-like limbs and deep sunken eyes. They wield swords as well as huge maces and act as Bolg's main enforcers.
Legolas and Tauriel go to the fortress in Mount Gundabad to scout on Bolg. At night, Bolg commands the forces of Gundabad to march forth and legions of orcs along with other foul creatures are seen leaving the pass to Angmar and follow their leader to Erebor. These armies of Gundabad Orcs are later seen marching upon the battlefield near Ravenhill. However, they are quickly engaged by Beorn and the Great Eagles led by Radagast,and their forces are soundly defeated. The remaining orcs scatter into the mountains.
