 " Phantom Lord " is a lyrical nod to devilry . The song begins with synthesized bass drone and contains a middle section with clean , arpeggiated guitar chords . Written by Mustaine , its central riff is in NWOBHM fashion . " No Remorse " is a mid @-@ tempo song which suddenly accelerates its tempo in the fifth minute . The song is about not feeling any remorse or sense of repentance during battle . " Seek & Destroy " was inspired by Diamond Head 's " Dead Reckoning " and is the first song Metallica recorded during the Kill ' Em All sessions . Hetfield wrote the main riff in his truck outside a Los Angeles sticker factory where he was working . Because of its simple , one @-@ line chorus , the song became a permanent setlist fixture and a crowd singalong . " Metal Militia " , one of the fastest songs on the album , is about heavy metal 's way of life and nonconformity . Mustaine composed the main riff , which emulates a marching army . The song ends with tramping feet and bullet ricochet in a fade @-@ out .
