Andy Johnson
Andy Johnson served for 29 years in the RAF, including 17 years on the Boeing Sentry AWACS, with operational flying in the Bosnia, Kosovo, Afghanistan and Iraq conflicts. He left the RAF in 2009 to become a full-time battlefield guide.
Andy has guided school, adult and military groups, small and large, to visit First and Second World War battlefields, with a particular interest in Normandy, including the D-Day beaches, air operations, and the frequently neglected inland fighting. He has also led tours from Arnhem and the airborne carpet to the 1945 battles on and across the Rhine. He has been privileged on three occasions to take veterans to their battlefields in Normandy and Monte Cassino. What an honour!
With a flying background, Andy has a huge interest in the air war and has led tours to sites related to the Great War in the air, Fighter Command, the Combined Bomber Offensive, the Battle of the Atlantic and the German secret weapons programmes. He enjoys bringing the air war to life, not just from the point of view of the commanders, planners, ground crew and aircrew, but also that of those at the receiving end.
An interest in the Air War naturally leads to an interest in National Socialist Germany, including the development and deployment of the V-Weapons, through the concentration camp and forced labour systems to the Final Solution. It is a difficult but important subject.
For most of his adult life, Andy has been a traveller and he has travelled widely in India, leading to a deep interest in the history of Great Britain’s involvement in that country. He has led groups looking at the story of the Indian Corps on the Western Front.
Andy completed the International Guild of Battlefield Guides validation programme in November 2011 and holds Badge No 52. He has acted as Validation Secretary since 2020 and in 2025 he He was elected a Fellow of the Guild at the 2025 Annual Conference.
