Angmar Shortpikes
Unlike other Orcs of the misty mountain, this larger breed of Orcs from the former realm of the Witchking of Angmar are heavily armoured, well trained and relatively well disciplined soldiers, who wield their short pikes with some skill.
Beornings - like the old unit, but now with dogs!
Beornings, are a race of men who are descended from Beorn from whom they inherited their name and their love for the animals of the land. Therefore, when they go to battle, they are accompanied by the great dogs, that in times of peace guard their homes. In those times they dwell in the Vales of Anduin between Mirkwood and the Great River and guard the passes of the Misty Mountains from Orcs and Wargs.
Black Uruks of Moria
Black Uruks, powerfull and fast, the fellowship encountered these fearsome creatures in the mines of moria during the attack on Balins tomb. Sent from mordor, to ensure the dark lords will is carried out in the north, equiped by the massive resources of the mines of moria, these are some of the most fearsome warriors located in the misty mountains.
Dale Axemen
Any true northman is a warrior first and a farmer, trader or boatman second. The culture of warfare is taught in the very air of the north, it is sung of in every song from time immemorial. For Dale, the axe could be just as much the symbol of their nation as the bow. These axemen are simplistic but rough and ready soldiers who can be raised from the masses and sent out to fight in a short time. Although they have limited skills on the field they are a well suited to fight armoured opponets.
Durthang Archers
Durthang Archers are well trained Uruks with good defensive skills and armour. They form the elite of Sauron's Orcish armies.
Horseguard of the Men-i-Naugrim
The Old Forest Road, also known as Men-i-Naugrim ('Dwarf-Road') in Sindarin, was the name of the east road where it passed through the Anduin at the Old Ford and then through Mirkwood. The Enchanted river intersected it at a marshy point near the River Running. After Sauron's occupation of Dol Guldur, the forest of Mirkwood became more and more dark and dangerous, so most chose not to travel upon the Old Forest Road for fear of being attacked. Therefore a company of Heavy Horse Archers has been tasked with the duty to ensure secure passage. Those soldiers are mounted on swift horses and wear medium armour, suitable to be deployed quickly wherever needed, and to defeat most enemies before even being reached, but with some staying power in melee too.
Ungol Slavemasters
The Slavemasters of Cirith Ungol are Orcish swordsmen in good armour, who are trained to ambush their enemies. If they are not hunting slaves, their job is to guard the prisons of Cirith Ungol.
Black Numenoreans of Umbar
After the Rangers of Ithilien started their guerilla campaign against Sauron's forces west of the Anduin, he sent his secretive Black Númenorean Rangers, Dark Númenorian men of Umbar, to counter this threat. Silent, deadly, these archers wear heavier armour and have sturdier bows than the rangers of Ithilien, allowing them to get closer to the action, and prevail in the bloody close combat that often occurs when bands of Dark Rangers and Ithilien Rangers meet.
Twilight Guard
In the eerie golden half-light of Lothlorien, an elite band of Elven Knights keep guard in the very centre of Caras Galadhon. The Twilight Guard are the personal retainers of Galadriel and Celeborn since they left out of Valinor, many Ages ago, and as such, are some of the greatest warriors known by elf-kind.
Haradrian Desert Cavalry
A company of lightly armoured semi-professional spear-cavalry of the southern deserts. Riding on sturdy camels they provoke terror amongst horses.
Wainrider Chariots
The Wainriders were a confederation of Easterling tribes who were united by their hate of Gondor, fuelled by Sauron. Following the Great Plague which weakened Gondor, they started their raids in 1851 of the Third Age and attacked in full force five years later, defeating the Gondorian army and killing King Narmacil II. They rode in great wagons and chariots (which gave them their name), and raided the lands of Rhovanion, destroying or enslaving its people. Gondor gradually lost all of its possessions east of Anduin, save Ithilien, to them. The thirtieth king of Gondor, Calimehtar son of Narmacil, defeated the Wainriders in battle on the Dagorlad, buying some rest for his land.
However the Wainriders struck back in 1944, allying themselves with the Haradrim of Near Harad and the Variags of Khand. They managed to kill King Ondoher and both his sons, but instead of riding on to Minas Anor and taking the city, they paused to celebrate. Meanwhile, general Eärnil of Gondor's southern army had defeated the Haradrim and rode north to defend his king. He came too late to rescue Ondoher, but managed to surprise and defeat the Wainriders in the Battle of the Camp. Eärnil was crowned king a year later. After this defeat the might of the Wainriders was broken, and their confederation collapsed. Now that the easterlings once more threaten the people of the west, some of them fight in the old way again.
