This book, first published in 1990, is an incisive examination of NATO's strategy for the defence of the central front - the concern that has lain at the heart of NATO since its formation. Politically, the central front marked the post-war division of Europe into two competing blocs; militarily, it has represented the area of greatest force concentration and greatest threat. As NATO's strategic agenda changed with the end of the Cold War, the central front remained a critical concern. This book analyses the structure, strategy and doctrines of both East and West, and examines the relationship of NATO strategy to conventional force doctrines.
