English: A U.S. Air Force combat controller from the 21st Special Tactics Squadron stands by to provide support during a cargo and personnel airdrop at the Holland Drop Zone in Fort Bragg, N.C., April 13, 2015, as part of the Combined Joint Operational Access Exercise 15-01. CJOAX 15-01 is an 82nd Airborne Division-led bilateral training event at Fort Bragg, N.C., from April 13-20, 2015. This is the largest exercise of its kind held at Fort Bragg in nearly 20 years and demonstrates interoperability between U.S. Army and British Army soldiers and U.S. Air Force, Air National Guard, Royal Air Force airmen and U.S. Marines. Special Tactics combat controllers integrate air power into ground special operations for mission success, deploying into forward hostile areas to establish assaults zones, provide air traffic control capability, and control offensive airstrike operations.
