Answer
Klepacki composed three songs for Command & Conquer: Red Alert 3. These songs include "Hell March 3," "Soviet March," and "Rising Sun." Each song is distinct and memorable, capturing the essence of the game's factions and setting. "Hell March 3" is a powerful and energetic march that embodies the American spirit, while "Soviet March" is a more somber and menacing piece that reflects the Soviet Union's military might.
