As a legal officer in the Australian Army Reserve (now long retired), I personally encountered numerous aspects of Pauline Collins’s excellent work, The Military as a Separate Society, in particular the complicated questions raised by the extent of civilian institutional control over the military. This is a comprehensive work, and possibly the only one of its kind, to perform such a detailed analysis of the American and Australian experiences. Certainly at least for military legal officers, it is a compelling read. For those presently serving, it provides a valuable insight into the nuances of how these questions are viewed institutionally. For those who have left the service, this book vividly brings to life the vexed issues they likely were called upon to resolve, and it will leave them wishing that such a valuable resource had been available to them earlier.
