In addition to my books I've written nearly 50 military/military history articles covering ancient to modern era subjects (e.g. Strategy & Tactics, Armchair General, Modern War, World at War, and MCSGroup, a conflict simulation provider for the US DoD). I also acted as an on-screen consultant for Greatest Tank Battles (Season 3) for episodes on the Western Front's final WWII armor battles, and Michael Wittmann..
My primary military interest is on the Second World War (Europe), First World War, American Civil War, and Thirty Years' War.
