Put it at the very start of an entrance or reveal, before any dialogue or action begins. Follow it with the Metal Gear Alert Sound as the next alert in the sequence, then let the Yeah Reaction Sound answer the arrival once the scene settles. Keep the Air Horn Club Sample for a separate celebration later in the edit.

This is a single blast from a firetruck air horn, lasting just over a second, with a deep tone that cuts through other noise. It feels urgent and commanding, like an emergency vehicle forcing its way through traffic, and it makes a listener sit up at once. The short burst works as a jolt rather than a drawn-out wail, so it lands instantly with no picture to explain it.
