The clip is tied to Battlefield V through its file name and tags, and it preserves a short piece of German in-game voice dialogue built around keeping one's nerve. On soundboards, short lines like this tend to travel because they are easy to recognise, easy to drop into a stream and short enough to work as a reaction without interrupting play. This one survives for the same reason: the phrase is simple, the advice is universally understood by players, and its calm tone makes an effective contrast with the frantic action of a shooter match.
