The Royal Air Force Regiment (RAF Regiment) is part of the Royal Air Force and functions as a specialist corps founded by Royal Warrant in 1942. The Corps carries out soldiering tasks relating to the delivery of air power. Examples of such tasks are Non Combatant Evacuation Operations (NEO), recovery of downed aircrew (Joint Personnel Recovery - JPR), and in-depth defence of airfields by way of aggressively patrolling a large area of operations outside airfields in hostile environments. In addition the RAF Regiment provides Joint Terminal Attack Controllers (JTACs) to the British Army and Royal Marines, and provides flight size commitment to the Special Forces Support Group.
