There are numerous Order of Battle books on the market. So what makes this one so special? Why should one decide on this particular book? Most Order of Battle books usually deal only with the division and corps level of a country's army. Most higher commands are not covered. This book deals with all the branches of a country's military, giving a breakdown of all the major echelons of command, from theater down to brigade, under each component (army group, armies, corps, division, and brigade), and the equivalent command structure for the other military branches are included.

Second, it attempts to give an overall command structure of the country's military, showing the central headquarters command structure as well as the major components (army groups, armies, corps, etc.)

Third, most Order of Battle books list the commanders and their dates of tenure. This book includes those but also lists their next duty assignments or where they went after leaving the post. One can literally trace a general officer's career through the upper echelons of command, making this completely different from all the other Order of Battle books on the market.
