Command & Conquer: Red Alert 2 was released by Westwood Studios in 2000 as the sequel to Red Alert. In the Allied campaign the Grand Cannon is France's special defensive structure, a huge fixed artillery turret with longer range and splash damage than the standard Prism Tower. Its distinctive firing sound was designed to match that scale. The clip later spread through RTS forums, YouTube gameplay videos and soundboards, where fans of classic strategy games still use it as a nostalgic shorthand for overwhelming base defence.
