SCHOFIELD BARRACKS -- Col. William J. Mangan took command of the 500th Military Intelligence Brigade on July 17 from Col. Patricia A. Frost at Weyand Field, Schofield Barracks Hawaii. US Army Intelligence and Security Command, Commanding General, Maj. Gen. Stephen G. Fogarty hosted the change of command ceremony. During her speech, Frost thanked Fogarty for his participation in the ceremony and the opportunity for her to continue to serve INSCOM as the G3. Although leaving her command proved difficult, Frost looks forward to her upcoming assignment. "It is very difficult to step away from command, but it is a little easier knowing that I will be able to continue to serve not only this brigade, but also the other 15 INSCOM Brigade Commanders," Frost said. "I am ready for the challenge." Frost also welcomed Mangan, who recently attended the Naval War College in Newport, Rhode Island and previously served as the Deputy Brigade Commander/Rear Detachment Commander, XVIII Airborne Corps, 525th Battlefield Surveillance Brigade. Mangan thanked the brigade Soldiers for their efforts in representing the brigade and ensuring the ceremony's success. "To the Soldiers standing here today representing the brigade... Thank you!" Mangan said. "You look great, are doing well and we appreciate your efforts in making this ceremony possible." Mangan went on to thank his successor for the impact she had during command. "Col. Frost, I also want to extend my personal thanks on behalf of the countless Soldiers, to include myself," Mangan said. "You and your Family have impacted not just here in the 500th Military Intelligence Brigade, but other formations in the Pacific you have led or influenced."
