Green Armyball was a ball during the Russian Civil War who wanted to protect it’s own clay from Soviet Unionball and White Movementball. He lost.
In the Russian Civil War, even though he was a Peasantball, Green Armyball never allied with Soviet Unionball nor White Movementball. Instead he fought against them, presumably in the woods (that's how he got his name). The one time he did ally with someone was with Free Territoryball, but mostly because of the fear of Soviet Unionball and White Movementball.
