The Bureau Central de Recrutement du Royaume de Belgique was the Belgian recruiting office in London during World War I. The office was where Indiana Jones and Remy Baudouin enlisted for the Belgian Army in 1916. Jones came up with his nom de guerre "Henri Defense" at the office having seen a sign with the word 'Defense' on the back wall. The recruitment officer present did not believe Jones, but enlisted him as Henri Defense anyway.
