(Tribune News Service) — Soldiers with the U.S. Army Special Operations Aviation Command said goodbye to the command's fifth chief warrant officer as it welcomed its sixth Friday. Col. Philip Ryan, the unit's commander, oversaw the change of responsibility from Chief Warrant Officer 5 David Greenwood to Chief Warrant Officer 5 Wade Ziegler during a ceremony held Thursday at Fort Bragg. The chief warrant officer spot was established in 2005 when Chief Warrant Officer 5 Carl Meyer was appointed to the 160th Special Operations Aviation Regiment, Ryan said. A similar slot was also established at headquarters, Ryan said.
