Colonel Douglas A. Macgregor PhD. is a retired American senior military officer and author. Recognized by one writer as one of the most influential military thinkers of the late 20th and early 21st Centuries. Former Speaker of the House, Newt Gingrich characterized Macgregor as being, “To the information age joint military what Billy Mitchell was to airpower and what Liddell Hart, Fuller, DeGaulle and Guderian were to armored warfare.”

Macgregor’s seminal work, Breaking the Phalanx: A New Design for Landpower in the 21st Century (Praeger, 1997) was the first book by an Active Duty military author since Brigadier General William Mitchell, U.S. Army Air Corps, to challenge the status quo and set forth detailed proposals for the radical reform and reorganization of U.S. Army ground forces. His follow-on work, Transformation under Fire: Revolutionizing How America Fights (Praeger, 2003) expands on the concepts and ideas for reform and includes a foreword by a former British four-star general, Sir Rupert Smith.

Breaking the Phalanx with its foreword by Professor Donald Kagan, was quickly translated into Chinese and read by senior officers inside the People’s Liberation Army (PLA). Negotiations are reportedly underway to translate Transformation under Fire into Chinese as well. Transformation under Fire was translated by the Israeli Defense Force (IDF) into Hebrew. According to the IDF general who wrote the preface to the Israeli edition, had Macgregor’s concepts been implemented inside the IDF, the IDF’s recent intervention in southern Lebanon might have turned out differently.
