 Militia persons were normally expected to provide their own weapons, equipment, or supplies, although they may later be compensated for losses or expenditures.A related concept is the jury, which can be regarded as a specialized form of militia convened to render a verdict in a court proceeding (known as a petit jury or trial jury) or to investigate a public matter and render a presentment or indictment (grand jury).With the Constitutional Convention of 1787 and Article 1 Section 8 of the United States Constitution, control of the army and the power to direct the militia of the states was concurrently delegated to the federal Congress.
