This papercraft is the Uruk-hai bust, a larger and more advanced breed of Orc that appeared during the Third Age, used first by Sauron before the Great Years and then majorly by Saruman in his war on Rohan, based on the film “the Lord of the Rings“. The paper model was created by J. Ossorio.
Uruk-hai breathed harshly and deeply, and were enormously strong, tense creatures, top-heavy juggernauts with massive chest, neck, shoulder, and jaw development. They snarled and grimaced constantly, as they were in constant pain and their only relief lay in violence. Their gait was like walking uphill on narrow poles, probably because as soon as they were spawned they were locked into heavy plate armor, so there was a perceived sense of crushing weight and momentum to their stride. They had difficulty turning quickly. They probably had limited formal training, just basic drill work, but they were lethal, instinctive fighters, much more dangerous than [common] Orcs. They used their falchions and spiked shields pretty much interchangeably, smashing and bashing. Their defenses were power blocks - no finesse, no deflections, just brutal chops that could bounce an attacking weapon back the way it came.
Sometimes they didn't even bother to defend themselves; they just relied on their armor and moved straight into the attack. They would hammer and chop, and occasionally flip their swords around and use the back-spike to pinion an enemy, or gut them with the prongs on their shields. In the books, they were described as black skinned, had slant eyes and hated Goblins and called them hole maggots. Also in their book description, they were armed with bows made of yew, short-swords and spears. Some had iron collars. It is possible in Tolkien's books, they possibly looked different equipment-wise. When Ugluk said "We are the fighting Uruk-hai! We slew the Great Warrior. We took the prisoners. We are the servants of Saruman the Wise:The hand that gives us man's flesh to eat. We came out of Isengard, and led you here, and we shall lead you back by the way we choose." must have made the orcs afraid, meaning they had to do what the "...cursed Isengarders!" told them to, or Ugluk would have to "...knock off a couple more heads!".
