The Adjutant was published from 1968 (volume 1) to 1999 (volume 28) by the Army Ornithological Society (AOS). At that time, the AOS and the Royal Air Force Ornithological Society (RAFOS) began to publish a join publication named Osprey (Armed Forces Bird Watching & Ornithological Journal) and the AOS ceased publication of The Adjutant. In 2008 the RAFOS made it known that it could no longer continue publication of Osprey due to lack of funding. The AOS voted in summer 2008 to re-establish The Adjutant and simultaneously merge it with the AOS's other publication, the Bulletin (Walker 2008, The Adjutant). The first volume of the restarted publication was volume 29, published in 2008.
