United States military seniority
Alexander Vandegrift is also frequently included in historical seniority lists due to his status as the first Commandant of the Marine Corps to hold a four-star rank, as is Anna Mae Hays who was the first woman to be promoted to brigadier general in the history of the United States. Historical seniority is rarely referred to after the Korean War since modern military seniority systems had been well-established after the mid 20th century. Expanded seniority lists such as the one listed below do exist mostly in recognition of major military leaders of modern wars and conflicts.
