It's hardly mutually exclusive. Many military problems are simply human problems and because of their low tolerance for error, military systems are often very good solutions that provide large non-military benefits. The DoD needed a better way to navigate, so they invented GPS. They needed more robust communications, so they funded the internet. They needed to predict the weather to plan operations, so they funded weather radar and satellites. Even the US interstate system was supported in large part because the military wanted to have fast easy cross country logistics.
