Cesar Campiani Maximiano and Ricardo Bonalume are two Brazilian-based journalists and historians who have spent several years investigating this subject with the former completing his PhD dissertation on the Brazilian Expeditionary Force. Ramiro Bujeiro has become a frequent and popular contributor to Osprey Military's book series since illustrating Warrior 23: US Marine in Vietnam (1998). He is an experienced commercial artist who lives and works in his native city of Buenos Aires, Argentina. His professional background includes many commissions as a figure illustrator and strip cartoonist for clients all over Europe and the Americas, including many years' work for IPC Magazines in Great Britain.

In the English-speaking world, it is generally unknown that a volunteer Brazilian Expeditionary Force (FEB) fought alongside the US Army in Italy from mid-1944 until the end of the war. This was in effect a light infantry division, consisting of three infantry regiments augmented with artillery and light armour. It was supported by a Brazilian Air Force contingent of a light reconnaissance squadron as well as a P-47 Thunderbolt-equipped fighter squadron. Although all weapons, uniform, kit and equipment were either American-supplied or American models, there were distinctive Brazilian adaptations to uniforms and other key pieces of kit. This is a seriously researched volume on a little-studied subject matter complete with a range of previously unpublished photographs and specially commissioned artwork plates.
