The Flag of the Earth Federation is a patriotic banner that consists of a teal background with a serrated top and bottom with the seal of the Earth Federation.
When an Earthforce soldier dies, the flag is draped over over a photon torpedo casket before the casket is shot into space.
The flag is also present at official ceremonies, such as the court martial of several Fire Nation, Earth Kingdom and Water Tribe people and the induction ceremony when the Vaadwaur survivors decided to be civilians in the Earth Federation.
On Cestus III, the flag is flown at the beginning of a baseball game. They also played the Anthem of the Earth Federation, taking their hats off and facing the flag.
