The Air Intelligence Wing of the Defence School of Intelligence (DSI) delivers the Joint Air Intelligence Course (JAIC) to officers and the Operational Air Intelligence Course (OpAIC) to airmen. These courses prepare the individual for posting to intelligence roles. After completion of the first tour of duty, airmen can choose to further specialise in Imagery or Signals Analysis. These Phase 2 specialist courses are delivered in the joint environment alongside intelligence specialists of the Royal Navy, British Army or Ministry of Defence civil servants.
