Macgregor has captured the attention of key leaders and inspired a genuine public debate on military reform. With the dangerous world situation of the early 21st century-and possible flashpoints ranging from the Middle East to the Far East-interservice cooperation in assembling small, mobile units and a dramatically simplified command structure is essential.
