About this site
agentai.army is an independent reference built from official sources: U.S. Department of Defense and service rank structures, the Defense Finance and Accounting Service pay-grade tables and the ICAO spelling alphabet. Pages are reviewed when the services change a rank or title; the last review date is in the footer. Earlier policy essays on military artificial intelligence were retired in October 2026.
