guard

A ceremonial guard in a tall black hat, unmistakably modeled on the British Queen's/King's Guard at Buckingham Palace, used for anything related to formal ceremony, stoic seriousness, or 'staying silent no matter what' jokes referencing the guards' famous refusal to react to tourists. Trivia: this emoji's design is so specifically British that it's one of the few emoji tied to one country's cultural institution rather than a generic global concept.
