 While working on Covert Operations , Klepacki composed Hell March from the idea of " a rock tune to marching boots , " finishing the song in one day after inventing the guitar riff . Upon listening , director Brett Sperry insisted this song be used as the signature theme of Command & Conquer : Red Alert . Originally intended for use with the Brotherhood of Nod , it features militaristic samples — including marching , industrial sounds , and a commander shouting orders . Klepacki initially scored Red Alert with sci @-@ fi camp in mind , but early songs were shelved . He switched gears to write gritty pieces , prompting the Red Alert team to expand upon the style of Command & Conquer . In preparing to compose , Klepacki acquired new sample libraries for unique and strange sounds . Particular creative moods would result in a few songs at a time . He first wrote heavy songs like Workmen and Crush , then composed neutral , synthesizer @-@ laden music , such as Vector and Roll Out . Klepacki scored <unk> and Mud , one of his personal favorites , before finishing with Militant Force and Radio 2 . He took breaks from working to make cameo appearances as a Soviet soldier killed by Kane and an Allied commander in the cut scenes of Red Alert . He previously appeared as a Nod soldier and the voice of the commando in Command & Conquer and would voice bit parts in future Westwood games .
