Place this clip on its own in an edit, after the action it marks, and keep the surrounding edit simple so the clip stands on its own as the marked moment. Use it once per edit, so the marked moment stays clear.

This is the short clip listed as Halo Reach Sniper Spree, lasting about 1.8 seconds and presented here as a single tappable sound button. It is listed under games, and this page gives the clip by that name and length alone, without adding a description of its voice or content beyond the title itself.
