A satirical anti-war song, "Welcome to Hell" tells the story of Tristan Bongo, a soldier who engages in hedonistic acts while on shore leave to dull the trauma he has endured during war.

Described by Consequence as having "mathy rhythm section and a searing breakdown", "Welcome to Hell" is a rock song with avant-garde and progressive elements, and an outro reminiscent of thrash metal.

[3] Frontman Geordie Greep explained in an interview the perspective of the song's narrative[4] being inspired by George S. Patton: The person speaking is a senior officer berating a junior one about his lack of involvement in this kind of merriment.

It's conveniently italicized, so you know it's a different scene.Through this narrative, Greep provides an avatar for the audience that is unaccustomed to those things, and is eventually dishonorably discharged from his service, begging the question: What does all the violence and mayhem truly serve at the end of the day?

"Welcome to Hell" has received praise, being referred to in Paste's review of Hellfire as "arguably the album’s most concise mission statement, [and] among the finest songs the band has released to date".
