Georg Bruchmüller was a German artillery officer who greatly influenced the development of modern artillery tactics. He was nicknamed Durchbruchmüller, a combination of the German word Durchbruch (breakthrough) with his name.

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.
