Hutier Tactics-
Infiltration attacks began with brief and violent bombardments of the enemy front lines, to suppress and demoralize the soldiers stationed there. Light infantry led these attacks. They would attempt to penetrate enemy weak points to bypass and isolate heavily defended positions in the front line. Other reinforcements would then enter these breaches, and the entire enemy line would shortly collapse. The attacks relied heavily on speed and surprise.
Royal Air Force / Strategic Bombing-
The British RAF developed its doctrine of Strategic bombing which led to the construction of long-range bombers and became the basic philosophy in the Second World War. The goal of strategic bombing was to defeat a nation by crushing its economy and its public's will to fight.
The Hundred Days Offensive-
The Hundred Days Offensive was the final period of the First World War, during which the Allies launched a series of offensives against the Central Powers on the Western Front from 8 August to 11 November 1918, beginning with the Battle of Amiens. The offensive forced the German armies to retreat beyond the Hindenburg Line and was followed by an armistice.
