Disposable Heroes was released by Metallica on their third studio album Master of Puppets in 1986 and is sung from the perspective of a young soldier used as cannon fodder in war. The track became a staple of the band's thrash metal catalogue alongside the album's title track. Remastered editions renewed interest among younger listeners, and short excerpts now circulate on soundboards and social edits where a burst of classic metal signals power, rebellion or an escalating fight scene.
