A military retirement pension earned after completing twenty years of active-duty service in the United States Army provides a secure, guaranteed monthly income for life. Under the traditional high-three retirement system, a soldier retiring at twenty years typically receives fifty percent of their final average basic pay of their highest three earning years. The exact monetary amount varies significantly depending on the service member's final rank, pay grade, and cumulative years of cumulative leadership service, supplemented by lifetime healthcare and veterans' assistance benefits.
