Col. David Marttala, 732nd Air Expeditionary Group commander and Lt. Col. Dustin Sutton, 732nd Expeditionary Security Forces Squadron commander roll up the guide on for the casing of colors ceremony July 31, Joint Base Balad, Iraq. When a military unit is inactivated, it is traditional to hold a casing of the colors ceremony, which includes a reading of the history of the command, before the unit’s distinctive flag, or “colors,” are furled, or “cased” in a protective sheath.
