Put it at the end of a charge montage, just as the plan collapses, then cut straight to Bruh for the deadpan reaction and Emotional Damage when the defeat sinks in. Keep it as the climax of the sequence, not the opener, so the other clips set up the fall.

This short clip delivers the Warhammer 40,000 battle cry 'For the Emperor' in a booming, exaggerated voice, lasting just under three seconds. It feels triumphant and absurd at once, like a tiny soldier shouting far beyond his size, turning a grim war slogan into a joke. It comes from the long-running 'Spess Mehreen' meme that playfully misspells Space Marine.
