Allied Operations refer to military actions conducted by a coalition of nations working together towards a common goal, particularly during conflicts like World War I and World War II. These operations often involve coordinated strategies, sharing of resources, and joint planning to achieve military objectives against a common enemy. Key examples of Allied Operations include the D-Day invasion in 1944, where forces from the United States, United Kingdom, and Canada landed on the beaches of Normandy to liberate occupied Europe. Such collaborations have historically emphasized the importance of unity and cooperation among nations in achieving victory in warfare.
