The composition, a work by James Hetfield and Lars Ulrich, has a total duration of 6:27, a journey that allows you to explore its different facets.

This track has found a special place in the gaming community, as the musical theme of the first level of the video game *Doom* was directly inspired by the main riff of this song. The lyrics, for their part, delve into the mindset of someone caught in the midst of a war conflict, feeling no remorse for actions committed in battle, even when facing the enemy. The song even generated some controversy in the United States, being associated with a criminal act where the perpetrator sang this song while committing a murder, and even repeated it when being sentenced.
