Battlefield V, released in 2018, is a Second World War first-person shooter, and Achtung is the German word for attention or watch out, used as a battlefield warning. Short clips like this spread through gameplay videos and soundboards because they are instantly recognisable as a call to look out, much like an enemy spotted warning or a danger alarm in other games. Creators keep reusing it because the single shouted word needs no translation to convey urgency, making it a compact alert for edits, streams, and memes about imminent trouble.
