The major powers had indeed employed strategies and tactics throughout the war depending precisely with their objectives, resources and geographical location they were in. The Allies – the United States, the Soviet Union, and Britain – inclined to use strategies of exhaustion and numeric superiority and a large scale attack on multiple fronts. Key participants such as Germany, Japan and Italy focused on speedy and forceful operations that aimed at achieving monopolized victories during the early stage of the war.

Germany adopted the style called ‘Blitzkrieg’ (Lightning war), which means an attack which combines both air forces, including armor and infantry which are supposed to bog down the adversary. It emerged strong in the Europe initially but overstretch, including the invasion of the Soviet Union, and inability to absorb lessons for a long war led to key defeats especially at Stalingrad and Kursk.

Japan used the strategy of unexpected strike and the naval superiority and the attack on Pearl Harbor was perfect example for early successes for Japan in the pacific. But they failed to produce industrial out put equal to USA and the tide changed near Midway which badly damaged their position.

Some of the examples of the Allied techniques include the “island-hopping campaign” in the Pacific; the “Normandy invasion” in Europe that benefited from multiple advantages and cooperation. The barbarous Soviet defenders repulsed Germans at Stalingrad, and an equally ferocious counterattack extinguished the Wehrmacht on the Eastern Front.
These tactics have caused the terrible devastation of the Axis powers, tremendous deaths and damages, and new world organization that resulted to a cold war.
