The Joint Helicopter Support Unit (JHSU) is a joint organisation of the British Army and the Royal Air Force, located in RAF Odiham.
It was formed in July 1982, following the introduction of the Chinook HC MK1 Helicopter. Personnel were drawn from the Royal Corps of Transport (RCT) and Royal Army Ordnance Corps (RAOC) (both now amalgamated into the Royal Logistic Corps (RLC)) and the Royal Air Force (RAF).
The RAOC were employed for their knowledge of Supply Systems - both Army and RAF, while the RAF Movers were employed for their knowledge of internal loads, and to act as an interface with the aircrew.
JHSU is currently structured on a 70/30% ratio. The 70% is of Army origin and comprises of several different capbadges, currently ranging from the Royal Logistic Corps (RLC), Adjutant General Corps (Staff and Personnel Support) (AGC(SPS)) to Infantry soldiers from The Green Howards, The Royal Regiment of Fusiliers (RRF) and the Household Division. In adition there is a small attachment of Royal Electrical Mechanical Engineers (REME), providing equipment support, Royal Artillery and the Royal Engineers. The RAF provide personnel from the Movements, MT Tech and Clerical trade groups.
