Changes in Shaw's commands
U.S. Air Force Maj. S. Nathan Puwalowski, 20th Security Forces Squadron commander (right), receives the 20th SFS guidon from Col. Scott Arcuri, 20th Mission Support Group commander, during a change of command ceremony at Shaw Air Force Base, S.C., Aug. 21, 2014. The tradition of passing the guidon goes back to 18th century Prussia; during this time, organizational flags were developed with color arrangements and symbols unique to the particular military unit.
