Place this clip at the end of a replay sequence, right after the failed push is shown in full. Lead into it with the Enemy Spotted sound when the army first appears, then let this laugh close the segment before the next play begins.
About this sound
This is the French version of Taunt 11 from Age of Empires II, a just-over-a-second recording of hearty male laughter with no words at all. It feels amused and lightly mocking, the kind of laugh that turns a boast or blunder into a punchline for everyone listening in the match.
