Webster's book is considered a leading source on the topic, and it should be noted that it is not for beginners. That said, it ought also be noted that it is not for the advanced student, either: those of us who have studied the Roman army in some detail will not find many new takes on the sources we have, except for a very interesting discussion of the Etruscan influence on Roman warfare, which I personally enjoyed a lot. As it stands, this book is a definite middle ground: excellent in its own right, but not adequately targeted to either audience. For a student of the Classics who has some background with Roman history this book will indeed be invaluable, but for graduate students and professionals it does not contribute anything radically new, no matter how elegant and stimulating as Webster's treatment may be.

The equites sagittarii formed a considerable force in the auxilia of the early and middle empire, but they, and particularly their role and employment, have received little scholarly attention. This paper will attempt to define their place on the battlefields of the high Empire. While horse archers are known to have been used in eastern armies such as the those of the Persians and Parthians with great effect, they were recruited into and employed by the Roman army in strength only starting at the reign of Augustus. Units of horse archers were almost exclusively recruited from eastern lands and were employed there as well, not only in war, but also as the border garrisons of Pannonia, Dacia, Africa, and the Levant.
