The ranks and insignia of the Sri Lanka Air Force are the military insignia used by the Sri Lanka Air Force. Upon the formation of the Sri Lanka Air Force in 1951, rank titles and badges for ORs were adopted from the Royal Air Forceofficer ranks and other ranks. Sri Lanka does have an Air Chief Marshal rank, but it is only awarded to the Chief of Defence Staff (CDS) or as an honorary rank; Air Chief Marshal Roshan Goonetileke was the only Sri Lankan Air Force officer to hold the air chief marshal rank while in active service.[1]
