Earth Kingdom supply truck



Earth Kingdom supply trucks are treaded supply vehicles designed by Sokka and the mechanist and fabricated at the Northern Air Temple by the latter. They made their first and only appearance in the Invasion of the Fire Nation, where they were primarily used to transport and supply earth and water for the bending factions of the invasion force.

History
At least eight of these trucks, driven by Earth Kingdom soldiers, were confirmed to have participated in battle during the Invasion of the Fire Nation. They trailed alongside the benders and dropped off water and boulders for use as weapons against the enemy. Trucks carrying fire bombs were used to blast holes into the walls separating the Royal Plaza from the Capital City, providing paths for the invaders. These trucks ensured that the invaders had a ready supply of bending material during the battle.

By the end of the battle, the solar eclipse had passed and the invasion force was defeated by the Fire Nation Air Force. It is unknown if any of these trucks survived the battle, though even if they did, they were likely to be captured by the Fire Nation.

Design
These vehicles were designed to carry weapons and bendable elements for use by the warriors and benders who made up the invasion force. It is possible they are operated somewhat like the earthbending-powered tanks, except the trucks drive entirely on treads. Each truck is driven by a single driver, is made entirely of metal, and possess a large flatbed that can carry earthen boulders, jugs of water, fire bombs, etc.

Connection
These trucks bear resemblance to tractor vehicles used by different factions during the Second World War, such as the Russian Voroshilovets Heavy Tractor. They are similar in design to real-world open-tray dump trucks, though presumably without a "dumping" mechanism, and with an open cabin, and they operate similarly to real-world trucks, with the exception of the treads.
