Royal Earthbender Guards

The Royal Earthbender Guards of Ba Sing Se, known commonly as the King's Guards, are Earthbender warriors within the Earth Kingdom and are affiliated with neither the Dai Li nor the military, but serve as personal protectors of the Earth King. There seems to be hundreds of them guarding the Royal Palace. They have also been seen as the gate keepers of the outer and inner walls of Ba Sing Se, and could also serve as guards in important events as shown when the Fire Nation attacked Ba Sing Se's walls with a drill and at Bosco's party. They sport a uniform different from a normal Earth Kingdom soldier, wearing heavier, dark green armor with a green feather at the top of the helmet. They also tried to prevent Aang and his group from reaching the Earth King. Later, some followed him around when he toured around the city along with Aang and his group. The guards use specialized surface-to-surface rocks against invaders approaching on foot, but the projectiles are displayed to be able to also serve as Surface-to-Air Rocks against airborne intruders.
