Army 365 Guidance

Army 365 Banner


The Army’s migration to Army 365 is a major Unified Network operations milestone and supports Army modernization by leveraging commercial services and technology. This transition better postures the Army as we shift our IT business model to managed services in order to leverage industry’s ability to adopt emerging technologies. Demands of constant training combined with short-notice deployments, the warfighter benefits from these Army 365 tools in order to operate anywhere, anytime and will eventually be able to do so on any device.
