The original soundtrack to The Rules of Engagement features an original score by Mark Isham, who also composed music for At First Sight, Blade, and Little Man Tate. Most of the score's pieces, such as &Gulf of Aden (USS Wake Island),& are rousing and martial, with a few quiet and poignant compositions like &A Hail Mary& and a few tense interludes like &Investigation.& Though Isham's score is appropriate for the film, it doesn't always work outside of the screen's context.
