The Great Wall Movie Tiger Corps

The Tiger Corps from The Great Wall movie belongs to The Nameless Order, a Chinese military order that was commissioned by the Imperial Court of the Song Dynasty during AD 1010–63. They were created centuries ago as a response to the arrival of the Taotie that had come to China on a meteor that crashed into the mountain. To protect against the alien horde, the Great Wall of China was constructed as a line of defense against the rampaging creatures with the Nameless Order manning it. 

The Tiger Corps are often seen in gold armour and are in charge of artillery, providing support for the other groups and utilizing the weapons which are hidden inside the wall, including fireballs and large blades.
