Air Force learning aviation materials refers to the majors of air force petty officers and pilots learning aviation equipment and maintenance technology, while World War IV refers to the military discipline of four-year undergraduate courses. Both have their own emphasis. The air force pays attention to training students' ability to maintain and manage aviation equipment and carry out related technical treatment. The Fourth World War was more about learning military theory, military command and political education. Which major to choose depends on personal interests and career planning.
