The armed forces is what protects the country day and night. You get a sense of relief that you are guarded by all sides of the country, whether land, water, or the skies. A salute to all the armed forces personnel who sacrifice their sleep and lives for their countries, and make us proud! One of them is the Royal Australian Air Force (RAAF). It was established in 1921. It is the second-oldest Air Force in the world, and the youngest among the three defense forces of Australia. Initially, it began as Australian Flying Corps. On March 31, 1921, it became known as the RAAF. The motto that appears on the Coat of Arms of the RAAF is "Per Ardua ad Astra". It means "Through Struggle to the Stars." The ranks help define a disciplined structure and hierarchy of any defense force in this world. The RAAF's rank structure was passed on to it from the Royal Air Force (RAF). The insignia are used to identify the ranks and are almost similar to that of the RAF, except that 'Australia' can be seen at the bottom of each insignia of every rank. The ranks are worn by the officers and airmen on their shoulders or sleeves depending on the rank. They are worn on all uniforms. In formal and official occasions, the Australian Air Force officers are addressed by their ranks followed by their names and family names. The ranks are abbreviated, but written all in uppercase and without any spaces unlike other defense organizations. They are segregated according to the seniority and degree of responsibilities. Let's have a look the ranks and insignia of the Royal Australian Air Force. This was in brief about the Air Force ranks of the RAAF. The rank of Marshal of the Royal Australian Air Force (MRAAF) is not an active rank, and is considered to be an honorary or ceremonial rank.
