The Prussian-style war of movement and quick strikes was well-designed for campaigns using the developed infrastructure of Western and Central Europe, such as the wars of unification, but failed when it was applied by the German Army to the Soviet Union and North Africa. The Prussian and later German systems were regarded as weak in intelligence, counterintelligence, and logistics, but during the First World War the German Army was often able to lay its hands on British and French battleplans. If the enemy successfully endured the initial operational attacks, the Prussian system had great difficulty in "Stellungskrieg", or war of position, though during the First World War those were not as pronounced.
