Joint Aviation Command
The Joint Aviation Command (JAC), previously known as Joint Helicopter Command (JHC), is a tri-service organisation uniting battlefield military helicopters of all three services of the British Armed Forces and unmanned aerial vehicles of the British Army for command and coordination purposes. The majority of the United Kingdom's military helicopters come under JAC, although exceptions include the Royal Navy's anti-surface warfare, anti-submarine warfare and airborne early warning helicopters and the No.
