Adrien Fontanellaz, from Switzerland, is a military history researcher and author. He developed a passion for military history at an early age and has progressively narrowed his studies to modern-day conflicts. He is a member of the Scientific Committee of the Pully-based Centre d’histoire et de prospective militaries (Military History and Prospectives Centre), and regularly contributes for the Revue Militaire Suisse and various French military history magazines. He is co-founder and a regular contributor to the French military history website L’autre cotè de la colline, and this is his tenth title for Helion’s @War series. Tom Cooper is an Austrian aerial warfare analyst and historian. Following a career in the worldwide transportation business – during which he established a network of contacts in the Middle East and Africa – he moved into narrow-focus analysis and writing on small, little-known air forces and conflicts, about which he has collected extensive archives. This has resulted in specialisation in such Middle Eastern air forces as of those of Egypt, Iran, Iraq, and Syria, plus various African and Asian air forces. As well as authoring and co-authoring more than 50 books - including an in-depth analysis of major Arab air forces at wars with Israel in period 1955-1973 - and over 1000 articles, Cooper is editor of Helion's five @War series. José Matos is an independent researcher in military history in Portugal with a primary interest in operations of the Portuguese Air Force during the colonial wars in Africa, especially in Guinea. He is a regular contributor to numerous European magazines on military aviation and naval subjects, and has collaborated in the major project ‘The Air Force at the end of the Empire’, published in Portugal in 2018. This is his first instalment for Helion.
