This book is a long-overdue account of, and a well-deserved tribute to, the Marine Corps sniper program in Vietnam. It documents the circumstances behind training and employment, the equipment chosen for use, the transition from the M700 sniping rifle to the M40A1 and the extreme effectiveness of the Vietnam-era sniping effort overall.

The late Peter R. Senich was recognized as one of the world's foremost authorities on the history of modern weapon systems and their applications. He was also a leading military historian and the author of nine books on military sniping and small arms.
