55th Operations Group welcomes new commander Published July 1, 2024 By Chad Watkins OFFUTT AIR FORCE BASE, Neb. -- The 55th Operations Group held a change of command ceremony July 1, 2024, at Offutt Air Force Base. Col. John “Ballgame” Isacco assumed command and Col. Derek “Bull” Rachel relinquished command in a ceremony officiated by Col. Mark Howard, 55th Wing commander. “We are expecting a lot out of you and we know we can get a lot from you because of who you are and the character that you have,” said Howard. “I can’t wait for what Ballgame has got for us, he’s going to be a fantastic leader.” Isacco previously served in various assignments on the Joint Staff. Prior to taking command, he was Reconnaissance Operations Division Chief to the Deputy Chief of Staff for Intelligence, Surveillance, and Reconnaissance Operations. Prior to this, he served a three-year AETC assignment as an academic instructor in the Department of Leader and Research Development at Air University's Air Command and Staff College where he directed ACSC’s Leadership in Command elective and taught core courses focusing on leadership and military strategy. Following his instructor tour, he graduated from the US Air Force’s Air War College. “Our family is excited to be back in Omaha, Nebraska. The elite performance at which the 55th Operations Group operates around the world is only possible via its incredibly talented Airmen. We're extremely grateful for this opportunity and proud to be part of such an amazing team,” said Isacco. Isacco hails from Greenville, Pennsylvania and received his commission from the United States Air Force Academy in 2001. He is a Command Pilot with more than 3,500 hours in E-3, RC-135 and trainer aircraft, including over 900 combat hours during Operations IRAQI FREEDOM and ENDURING FREEDOM. “To our Airmen, know that you are at the forefront of my mind always,” said Isacco. “I see your talent and honestly, I am in awe of it. And as we put the Wing’s vision into execution, the entire Air Force will see your talent as well.” The 55th OG operates five C-135 variants and executes global airborne intelligence, surveillance and reconnaissance, as well as treaty verification missions. It is the largest operations group in the Air Force with 11 squadrons and two detachments around the world. “It has been an honor and a pleasure to serve as the 55th Operations Group Commander,” said Rachel. “The exceptional Airmen in this group are critical to defending freedom, and I am thankful to have served alongside these true American heroes. The local community is world class and supports our military better than any other community I have served in. This position culminates a 28-year career. It has been an amazing journey for me and my family.” Rachel will retire on November 1, 2024. “Bull was custom made for this job,” said Howard. “We are so grateful to you and thank you for your over 28 years of service.”
