Put it at the turning point of an edit, just before the reveal or the consequence, then follow it with a sharp impact cue such as the tactical nuke incoming sound to underline the escalation, or cut to the drama sting for a contrasting finish.
About this sound
This is a short, roughly four-second clip of a German male voice delivering the line 'Wollt ihr den totalen Krieg?' in a loud, declamatory speech style. It feels tense and confrontational, with a sudden, rallying intensity that makes a room go quiet. The line comes from Joseph Goebbels's 1943 Sportpalast speech in Berlin.
