The line opens the Cerberus Vae III strike in Bungie's Destiny, released in 2014, where Commander Zavala briefs Guardians before fighting the Cabal on Mars. Players heard it repeatedly while replaying the strike, so the long, formal wording became a copypasta and snowclone online. Fans replace the ending with new enemies and places, post it under news stories and trailers, and use the audio on videos whenever someone is reluctantly pulled into a large, complicated conflict.
About this sound
Commander Zavala's opening briefing from Destiny about the war with the Cabal on Mars, now used as a meme intro for unavoidable battles and long tasks.
This clip is Commander Zavala's full strike briefing from Destiny, delivered in a flat, grave monotone as he explains the war with the Cabal on Mars and the plan to eliminate Valus Ta'aurc. The humour comes from how seriously he treats a routine mission, listing defences, commanders and an Imperial land tank without pausing. Dropped over unrelated footage, it instantly turns a minor errand, argument or chore into an epic military campaign, and listeners who know the game usually start reciting the rest from memory.
