Morocco has also been the venue for Exercise "Jebel Sahara" since September 2000, taken 10 times since, and gathering elements from 33 Squadron, 230 Squadron, 18 Squadron, 27 Squadron, Joint Helicopter Force HQ from RAF Benson, 1st Battalion Royal Gibraltar Regiment and 2nd Brigade d’Infanterie Parachutiste of the Royal Moroccan Army. The aim of the Exercise was to increase the Support Helicopter warfighting capability in desert 'hot and high' conditions and foster good relations between the UK and Morocco. To achieve this, the scenario consisted of a joint counter insurgency operation in the desert and mountain foothills to re-establish control and authority within a troubled region of North Africa. Another exercises were the "Jebel Tarik", with the Moroccan contribution of service personnel to an annual bilateral deployment of two companies (up to 180 personnel) of the Royal Gibraltar Regiment (RG) to the UK, on seven occasions since 2003. "Desert Vortex", a one-off bilateral helicopter exercise which is run between 16 May and 30 June 2009. This was a UK training exercise with objectives set by Joint Helicopter Command (JHC) and run concurrently with Moroccan Air Force annual helicopter crew training.
