During the Hundred Year War, the Fire Nation used these creatures as cavalry mounts or as beasts of burden, often decorating them in red. Komodo rhinos have been used in almost every Fire Nation military operation, such as the Siege of the North and the invasion of the Fire Nation, although they were most prominently used by the Rough Rhinos. Because of their widespread use by the Fire Nation Army, Fire Nation boot camps had an exercise designed to train new recruits in how to mount and ride a komodo rhino.
