It is played various times in Star Wars: Episode I The Phantom Menace as the Trade Federation Droid Army invades the planet Naboo. In Star Wars: Episode II Attack of the Clones, it is used to represent the clone troopers—and is played when Obi-Wan Kenobi first witnesses them in full armor on Kamino—who would form the Grand Army of the Republic as pawns of the Sith.
"Love Pledge and the Arena" from Attack of the Clones introduces a similar piece of music, "The Arena," which represents the Grand Army of the Republic. The piece also appears in Star Wars: Galactic Battlegrounds: Clone Campaigns as part of a medley of background tracks meant to represent each of the game's factions. In Star Wars: Battlefront, the theme is played when the Confederacy of Independent Systems wins Galactic Conquest.
The piece is also tracked into Star Wars: Episode III Revenge of the Sith as the Battle of Kashyyyk begins with a droid onslaught at Kachirho. Revenge of the Sith also plays the theme as Padmé Amidala makes landing on Mustafar.
