What new strategies did the allies use in the fight in Europe and North Africa?

During the fight in Europe and North Africa, the Allies employed several new strategies, including the use of combined arms operations that integrated air, land, and naval forces for coordinated attacks. The North African campaign saw the implementation of deception tactics, such as Operation Bodyguard, to mislead Axis forces about the timing and location of invasions. Additionally, the Allies adopted a strategy of "island hopping" in the Mediterranean, targeting key locations to establish footholds for further advances. This allowed for more efficient resource allocation and improved communication among Allied forces.
