Most generals have at least two decades of experience in the Army. As you gain experience, higher-ranking officers may give you the opportunity to grow in your ranks. Before becoming a general, you must become a brigadier general then a major general then a lieutenant general and finally a general. Before becoming a general, the president must nominate you. Then, the U.S. Senate needs to approve the decision. Since the Army limits how many generals can serve at once, you will only have the opportunity to serve once another general retires or passes away. Typically, generals must retire when they turn 62.
