In 1964 Military Assistance Command, Vietnam, activated a joint unconventional task force known as the Studies and Observation Group--MACV-SOG. As a cover its mission was to conduct analysis of lessons learned in combat involved all branches of service. SOG's real mission was to conduct covert strategic reconnaissance missions into Laos, Cambodia, and South Vietnam as well as sabotage and 'Black' psychological operations. Ground, air, and naval assets were employed to insert, collect, extract, and otherwise support these operations. Drawing on detailed, first-hand accounts of the experiences of the service, including action on operations, this book will shed light on one of the most crucial units of the Vietnam War.

Few tank designs have been as effective, versatile and long-lived as that of the British Centurion. Conceived during the Second World War as the answer to the superior German Tiger and Panther tanks and to the lethal 88mm gun, this 52-ton main battle tank incorporated the lessons British designers had learned about armoured fighting vehicles during the conflict, and it was free of the major faults that had impaired the other British tank designs of the time. The Centurion was so successful that it served in the British Army and in numerous other armies across the world from 1945 until the 1990s. Pat Ware's highly illustrated history of this remarkable tank covers its design and development, its technical specifications and the many variants that were produced. He tells the story from the design brief of 1943, through testing and trials to the tank's entry into service. And he traces the course of the Centurion's subsequent career as it was up-dated, up-gunned and adapted to operate in varied conditions and conflicts all over the world including Korea, the Indo-Pakistan wars, Vietnam and the Arab-Israeli wars. His expert account of this remarkable fighting vehicle is accompanied by a series of colour plates showing the main variants of the design and the common ancillary equipment and unit markings. His book is an essential work of reference for enthusiasts.

During the Old and Middle Kingdoms, Ancient Egypt led the world in the construction of fortifications. The oldest was discovered on Elephantine Island and dates to c.2900 BC. This book investigates over 2,000 years of Egyptian fortification, including both fortified cities and military installations. It covers the most famous sites, including the fortified town of Ayn Asil and the fortress of Buhen. The text also examines the specific defensive structures within the fortifications, including gates, walls, and towers, and looks at both the operation and social history of these ancient military strongholds. Maps, photographs, and artwork by Brian Delf recreate this long-lost but legendary era, a treat for the eye as well as the mind.
