The Joint Service Review is a parade and review by the Army, Air Force, Navy, and Marine Reserve Officer Training Corps. Units will assemble to celebrate the tradition of "inspecting the troops." The OSU ROTC Units are inspected by a guest reviewing official in a tradition going back to 1916. This year the Air Force is the host service. Invited guests will include state, local, and university dignitaries as well as local veterans and alumni of the various units.
