In warfare, infiltration tactics involve small independent light infantry forces advancing into enemy rear areas, bypassing enemy frontline strongpoints, possibly isolating them for attack by follow-up troops with heavier weapons. Soldiers take the initiative to identify enemy weak points and choose their own routes, targets, moments and methods of attack; this requires a high degree of skill and training, and can be supplemented by special equipment and weaponry to give them more local combat options.

Stormtroopers were specialist infantry soldiers of the German Army. In the last years of World War I, Stoßtruppen were trained to use infiltration tactics – part of the Germans' improved method of attack on enemy trenches. The German Empire entered the war certain that the conflict would be won in the course of great military campaigns, thus relegating results obtained during individual clashes to the background; consequently the best officers, concentrated in the German General Staff, placed their attention on maneuver warfare and the rational exploitation of railways, rather than concentrating on the conduct of battles: this attitude gave a direct contribution to operational victories of Germany in Russia, Romania, Serbia and Italy, but it resulted in failure in the West. Thus the German officers on the Western Front found themselves in need of resolving the static situation caused by trench warfare on the battlefield.
