Jet ski



Jet skis were a mode of water transportation in the Fire Nation's war arsenal. This steam-powered water skimmer was perfect for short-range water travel and warfare; seating two soldiers, it traveled at fast speeds and could reach a location via water very quickly. The device ran on steam power, as made evident by the boiler and fire box in the back. Although it had no visible armament, it was nonetheless a fearsome sight. The jet ski is presumably exclusive to the Fire Nation domestic army, as it was not used by the front-line forces, similar to real-world coast guard vessels and patrol boats.

History
When he suspected the villagers of sabotage, General Mung and his forces arrive at the village of Jang Hui on jet skis to destroy it in retaliation. In actuality, Katara and Aang had destroyed the factory. While still disguised as the Painted Lady, Katara fought the soldiers and destroyed several of their Jet skis during the battle, leaving only a few for the terrified assailants to escape on.

Jet skis were also used to intercept the Water Tribe fleet during the Day of Black Sun at the Great Gates of Azulon. While they captured the ships, the invasion force itself evaded the pursuers with their submarines.
