World War II Tanks: Western Allies 1939-45

David Porter's survey of Western Allied armour during the Second World War offers a comprehensive overview of the tanks fielded by the United States, Britain, Australia, Canada, France, and Poland between 1939 and 1945. The scope is ambitious, covering multiple national programmes within a single volume, and the author manages this breadth by organising the material logically, moving through the major vehicle types and their variants while situating each design within its historical and industrial context.

One of the strengths of this book lies in its treatment of the sheer diversity of Allied tank development during the conflict. Rather than focusing solely on the most famous designs, such as the American Sherman or the British Churchill, Porter also examines less celebrated vehicles and the contributions of smaller Allied nations. The inclusion of Polish and Free French forces, for instance, adds a dimension often overlooked in general histories of the war, which tend to concentrate on the two dominant Anglo-American programmes. This broader perspective helps illustrate how tank design and production were shaped not only by doctrine and industrial capacity but also by the political circumstances of occupied and exiled nations contributing to the Allied war effort.

The book's structure allows readers to trace the evolution of armoured vehicles from the early, often underpowered designs of the pre-war and early-war years through to the more capable machines that emerged by 1944 and 1945. Porter pays attention to the technical specifications of each tank, including armament, armour thickness, and mobility, while also addressing how these characteristics translated into battlefield performance. This technical detail is balanced with historical narrative, giving context to why certain designs were adopted, modified, or eventually replaced. The discussion of the Sherman's various marks, for example, reflects the ongoing efforts to address its vulnerabilities against German armour, while the coverage of British cruiser and infantry tanks highlights the persistent doctrinal debates within the British Army regarding the role of armour on the battlefield.

The inclusion of Commonwealth forces, particularly Australian and Canadian contributions, is a valuable addition. These nations often adapted or produced variants of British and American designs to suit their own operational needs, and Porter's attention to these adaptations demonstrates the practical challenges of coalition warfare. The Canadian Ram tank and the various Australian modifications to existing designs receive attention that is not always afforded in broader histories, giving the book additional value for readers interested in the less-documented aspects of Allied armoured warfare.

Visually, the book benefits from photographs and technical illustrations that support the text, allowing readers to see the physical characteristics of the vehicles discussed. These images complement the written descriptions, particularly when explaining modifications or distinguishing between different marks of the same vehicle. For readers with a strong interest in military hardware, this visual documentation is a useful reference point alongside the narrative.

While the book covers a great deal of ground, its comprehensive scope means that some individual vehicles receive relatively brief treatment compared to more specialised, single-subject works. Readers seeking exhaustive detail on any one tank type may need to supplement this volume with more focused studies. However, as a general reference covering the full range of Western Allied tank development, the book succeeds in providing a coherent and informative overview that connects design decisions to their historical circumstances.

Overall, this volume serves as a solid introduction and reference for those interested in the armoured vehicles used by the Western Allies during the Second World War. Its inclusion of lesser-known national contributions alongside the more familiar American and British programmes broadens the reader's understanding of how Allied tank forces were assembled from diverse industrial and political sources. The combination of technical detail, historical context, and visual material makes it a useful addition to the library of anyone interested in the mechanised warfare of this period, whether approaching the subject as a general enthusiast or as someone seeking a broader foundation before pursuing more specialised research.
