The German A7V and the British Mark IV were similar in weight, size, and speed, but differed significantly in armour, armament and maneuverability. The A7V had thicker armour, and had nearly double the horsepower per ton. The Mark IV's pair of side-mounted 6pdr cannons forced the vehicle to present its side arc to an enemy in order to fire one of its main guns. Possessing twice as many machine guns as the Mark IV, the A7V had a frontally mounted 57mm gun that proved capable of defeating the Mark IV's armour. The Mark IV's rhomboid design proved superior in crossing trenches, climbing obstacles and moving over rough terrain. As the first tank-versus-tank engagement in history, the fighting around Villers-Bretonneux showcased the British Mark IV and German A7V designs. Although not purpose-built to combat enemy armour, both vehicles proved the viability of such operations, which during the postwar period led to key advances in suspension, armour, gunsights, ammunition, and command and control. While the British continued to develop their armoured forces, German armour development never materialized, and only in the postwar period did they address the issue.

This book draws us into the dangerous world braved by American and North Vietnamese airmen in the skies over Vietnam. Influential leaders and tacticians are profiled to provide a comparative evaluation of their contrasting skills. This book also reveals the technical specifications of each jet with an analysis of the weaponry, avionics and survival devices of the F-4 Phantom II as flown by the USAF and the MiG-21. The fighters' strengths and weaknesses are also compared, including turn radius, performance at altitude, range and structural integrity. First-person extracts reflect on the dangers of these aerial duels, as USAF pilots and their counterparts struggled to overcome each plane's shortcomings.

The formidable Mark IV tank was pitted against the German Army from 1917 until the end of World War I. This book reveals the important role the tank played in the historic battle of Cambrai in 1917 as well as the first ever tank-versus-tank actions against German A7Vs. In awe of British technology, the Germans actively captured, salvaged and repaired Mark IVs for deployment against the Allies. Using rare photographs and detailed artwork, David Fletcher explores the Mark IV's design and development, its variants and accessories, and brings to life its exciting deployment on the battlefields of World War I.

This title looks at the Medium Mark A Whippet, one of the most successful British tanks of World War I and, when placed alongside existing titles covering the Mark I, Mark IV and Mark V, completes the New Vanguard series' coverage of the major British tanks of the war. The evolution of the Whippet is examined in detail, from design and development to mechanical details and crew duties, and information on the operational use of the vehicle is drawn from war diaries and battalion records. The Whippet was involved in several well-known incidents that will be presented in this volume, including the clash at Cachy on April 24, 1918, the actions of the 6th Battalion tank known as “Musical Box” on August 8, 1918, and Sewell's Victoria Cross-winning exploits with the 3rd Battalion on August 29, 1918. Mention will also be made of the Whippet's involvement with the Tank Corps' expedition to Russia. In addition to this examination of the Mark A Whippet is a study of the other Medium tanks up to the end of the war: the Medium B, Medium C, Medium D and the experimental American Studebaker tank.

Within months of the start of the First World War, Germany began to run out of the raw materials it needed to make explosives. As Germany faced imminent defeat, chemists such as Fritz Haber and Carl Bosch came to the rescue with Nobel Prize winning discoveries that overcame the shortages and enabled the country to continue in the war. Similarly, Britain could not have sustained its war effort for four years had it not been for chemists like Chaim Weizmann who was later to become the first president of the State of Israel. Michael Freemantle tells the stories of these and many other chemists and explains how their work underpinned and shaped what became known as The Chemists’ War. He reveals: • how chemistry contributed to the care of the sick and wounded and to the health and safety of troops; • how coal not only powered the war but was also an important source of the chemicals needed for the manufacture of explosives, dyes, medicines and antiseptics; • how Britain’s production of propellants relied on the slaughter of tens of thousands of whales; • how a precious metal played a critical role in the war; • how poisonous chemicals were used as weapons of mass destruction for the first time in the history of warfare and how chemists developed gas masks for protection against these weapons; • how the British naval blockade of Germany imperilled agricultural production in the United States. The book will appeal to the general reader as well as the many scientists and historians interested in the Great War.
