Given the question: Information:  - Operation Mincemeat was a successful British disinformation strategy used during the Second World War. As a deception intended to cover the 1943 Allied invasion of Sicily, two members of British intelligence obtained the body of Glyndwr Michael, a tramp who died from eating rat poison, dressed him as an officer of the Royal Marines and placed personal items on him identifying him as Captain (Acting Major) William Martin. Correspondence between two British generals which suggested that the Allies planned to invade Greece and Sardinia, with Sicily as merely the target of a feint, was also placed on the body.  - Glyndwr Michael ( 4 January 1909 -- 24 January 1943 ) was a semi-literate homeless man whose body was used in Operation Mincemeat , the successful World War II deception plan that lured German forces to Greece prior to the Allied invasion of Sicily . The invasion was a success , with Allied losses numbering several thousand fewer than would have been expected had the deception failed .  - World War II (often abbreviated to WWII or WW2), also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the world's nationsincluding all of the great powerseventually forming two opposing military alliances: the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. In a state of "total war", the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, erasing the distinction between civilian and military resources. Marked by mass deaths of civilians, including the Holocaust (in which approximately 11 million people were killed) and the strategic bombing of industrial and population centres (in which approximately one million were killed, and which included the atomic bombings of Hiroshima and Nagasaki), it resulted in an estimated 50 million to 85 million fatalities. These made World War II the deadliest conflict in human history.  - The Allied invasion of Sicily, codenamed Operation Husky, was a major campaign of World War II, in which the Allies took the island of Sicily from the Axis powers (Italy and Nazi Germany). It was a large amphibious and airborne operation, followed by a six-week land campaign and was the beginning of the Italian Campaign.    Given the paragraphs above, decide what entity has the relation 'military rank' with 'major'.
