"This book is a valuable work for the reference shelf and a bible for military buffs." (Greece & Rome, 2008)

“This volume is another in the growing range of period- or topic-focused Companions to the Ancient World published by Blackwell. The Roman army, as a central institution and influence in so many aspects of Roman imperial history, is an obvious subject for such a volume. Like other volumes in the series, this one boasts an impressive range of international authors, and the scholarship is of a very high order.” (New England Classical Journal, February 2009)

“It is no easy task to commission and co-ordinate 29 separate contributions, and the editor's energy in doing so should be recognized. The volume will happily sit on an academic bookshelf … as a handy compendium of the views of the individual authors.” (Bryn Mawr Classical Review, October 2008)

“The most extensive and likely best researched overview on the Roman army that is currently available.” (Ancient Warfare)

"Highly readable, informative, and up-to-date survey…The book constitutes an outstanding resource for many topics concerning the Roman army…there is much to interest laymen…and scholars alike.”

"It is particularly valuable in providing up-to-date accounts of the army's manifold aspect and the bibliographies to support them." (Scholia Reviews)
