Gareth has been a keen student of twentieth century warfare for many years. He served in the Royal Tank Regiment for over 25 years and his military career included tours teaching at Sandhurst, the Land Warfare School, and the Joint Services Command and Staff College, as well as two tours in the Ministry of Defence. He has an MA in Defence Studies from Kings College London.

Gareth now works as a Warfare Analyst, looking at current military challenges as well as helping people learn from the past. He regularly leads group tours for schools and military units as well as highly bespoke tours for individuals and families. His interests include command, learning, and technology; the Great War in France & Flanders, Italy, and Palestine; Second World War combined arms actions of 1944 and 1945; and tanks – because a day without a tank is a day wasted. His first book, on tanks in 1917, will be published by Helion in 2021.
