Description:I've found this book very useful as a quick reference guide to Roman Military theory and sources. Sort of like a Roman Sun-Tzu. The layout makes it easy to narrow down and select from the applicable writings. The only reason it's not a five-star is that the translations chosen on artillery are a bit simplistic and not really the best and most accurate. I can't speak with much authority about other topics, but in this narrow instance I'd prefer to see more detail. I suppose it is not the author's intent to break new ground, getting readers started in the right direction is a worthy effort.
