Final answer:
Fighting in Africa posed different challenges for American forces due to vast deserts, guerrilla tactics, and terrain harshness that impacted supply lines and mobility, unlike in Europe.
Step-by-step explanation:
The landforms in Africa presented unique challenges for the American armed forces during combat, contrasting significantly with the fighting terrain in Europe. In Africa, vast deserts and a substantial coastline, along with the involvement of African soldiers and resistance from local peoples, made warfare complex. Unlike the more predictable warfare in Europe with established fronts, in Africa, the American armed forces had to contend with guerrilla tactics, desert warfare, and the vastness and harshness of the terrain which affected supply lines, mobility, and strategies.
