Originally the German assault gun was designed as an infantry support weapon, but the changing conditions of the battlefields of the Second World War forced it to adapt to perform a number of different roles, most importantly as a tank destroyer, although the infantry support role was never wholly discarded. If the much-glamorised Panzer divisions were the sword of the German army then the assault gun and tank destroyer units were its shield. As the Panzers' grip on the battlefield began to fail, though, it was left to the assault gun and tank destroyer crews to take up the burden.

The Jagdpanzer 38 is one of the best known German armoured fighting vehicles from World War II. Rushed into series production in the record time of less than four months, it was instantly recognisable by the sleek appearance created by its well-sloped armour. Many experts in post-war armour hold the opinion that this tank destroyer was just the answer to Germany's problem of dealing with the numerically superior American M4 Medium tank (known to the British Army as the Sherman) and the Russian T-34.

As the Second World War dragged on, heavy German losses in armoured vehicles and tanks ensured that assault gun units had to play an increasingly vital role in supporting the beleaguered infantry and countering Allied armour, particularly on the Eastern Front. The Sturmgeschutz was one of the most numerously produced and effectively deployed of the German armoured vehicles. This book reveals how the Sturmgeschutz provided the backbone of Germany's armoured forces in every theatre and on every front during the long fighting-retreat of the final years of the war.

The Panzerkampfwagen IV was one of the most numerous and successful German tanks of World War II. Despite the introduction of the Panther and Tiger tanks, the PzKpfw IV remained the backbone of the German armoured units until the end of the war. This book details all of the variants of the Panzerkampfwagen IV with the long guns 7.5cm KwK 40 L/43 and L/48. Until 1942 armed with a short 7.5cm KwK L/24, it was used primarily in an infantry support role. However with the upgrading to the long 7.5cm it became the main battle tank of the Panzer Divisions.

From the moment that the M4 Sherman had been matched against German Panther and Tiger tanks, the American tank crews had known that their vehicles were outclassed by the opposition. What was needed was a more powerful tank, more heavily armed and armored, that could take-on the powerful German panzers on a more equal footing. Although it took time to develop by the latter months of the war numbers of M26 Pershing tanks were reaching the frontline US armored units. Well armored and with a powerful 90mm gun the Pershing was a match for any tank in the German order of battle.

Perhaps the most influential arm of either army in the prosecution of the American Civil War, the artillery of both sides grew to be highly professional organizations, centralizing their artillery, organizing artillery battalions from individual batteries and giving their commanders higher ranks than field artillerymen had previously held. In battle, the introduction of the 12-pdr. Napoleon, followed closely by rifled cannon, provided a range and power previously unknown on American soil. This book details this vital cog in the war-machine of both sides.

Because of the length of the coastline of the United States, from the beginning American ordnance and engineers placed an emphasis on heavy artillery mounted in coastal defences. The Union army organised its 'Heavy Artillery' into separate regiments, uniformed and equipped differently. While the Field Artillery was assigned across the fighting fronts Heavy Artillery units served the big guns in the forts and the defences of Washington. The Confederates did not differentiate types of artillery and those that became known as Heavy Artillery did so through informal association rather than formal...

The Medieval era was a period of huge variety and invention in siege warfare. Before the use of cannon and other gun-powder artillery, siege engines relied on assorted sources of power, from torsion 'energy storage' systems to man-power, counter-balances and others. This book reveals how technological traditions from the Graeco-Roman world, Persia, India and above all China made a massive contribution to siege warfare techniques. It also covers developments in military engineering, such as mining, counter-mining, the breaking of walls, the use of noxious and chemical fumes and the use of...

The first seagoing ironclad was the USS Monitor, and its profile has made it one of the most easily recognised warships of all time. Following her inconclusive battle with the Confederate ironclad Virginia on March 9, 1862, the production of Union monitors was accelerated. By the end of the year a powerful squadron of monitor vessels protected the blockading squadrons off the Southern coastline, and were able to challenge Confederate control of her ports and estuaries. Further technological advancements were included in subsequent monitor designs, and by the end of the war the US Navy...

The French Revolutionary and Napoleonic Wars encompassed a period when rival European fleets vied for naval supremacy, and naval tactics were evolving. The British Royal Navy emerged triumphant as the leading world sea power, and the epitome of Britannic naval strength was the Ship-of-the-Line. These 'wooden walls' were more than merely floating gun batteries: they contained a crew of up to 800 men, and often had to remain at sea for extended periods. This book offers detailed coverage of the complex vessels that were the largest man-made structures produced in the pre-Industrial era.
