Well, I planned and led the invasion of the Fire Nation. We were a smaller force, but we were using the element of surprise combined with the arrival of an eclipse to try and drive straight to the Imperial Palace when they would be unable to use their firebending. Unfortunately... they found out about our plan, somehow.

Besides that... I guess not much. Although between just three of us, we took out a dozen Fire Machine Airships before they could incinerate the Earth Kingdom.
