The Pennsylvania State Guard (originally known as the Pennsylvania Reserve Defense Corps) is the currently inactive official state defense force of the state of Pennsylvania, which was active during World War II and the Korean War. The unit was organized as a home guard composed of volunteers who were trained and organized as parallel to the state’s National Guard. As a part of Pennsylvania's official militia, the Pennsylvania State Guard was trained, organized, and funded by the state of Pennsylvania, answered to the governor, and could not be federalized or deployed abroad.
