Place it just after a command is given, at the moment a character accepts the task, then follow it with Enemy Spotted to raise the tension or Bomb Has Been Planted to move the scene toward the objective.
About this sound
This is a short Russian voice line in which a servant answers that he obeys, delivered in a flat, dutiful tone that makes the command feel accepted without question. It feels loyal, stern and slightly ominous, like a subordinate ready for a grim task. The line comes from Warhammer, where such obedient servants are part of its dark military world.
