Sergeant Dornan is the Enclave drill instructor encountered at Navarro in Fallout 2, the 1998 post-apocalyptic role-playing game from Black Isle Studios. Known for his relentless, profanity-laced inspections, he became a fan favourite for players who enjoyed the game's dark humour and unforgiving military satire. Clips of his shouting have circulated among Fallout fans and soundboard users for years, and the line remains popular as a short, instantly recognisable reaction for discipline jokes and gaming edits.
