Consisting of a small cadre of permanent force warrant officers and senior non-commissioned officers, along with the Australian Staff Corps, the AIC was tasked with providing training to the part-time soldiers of the Citizen Force of all arms and services, including combat and technical branches. Upon formation, the corps had an establishment of around 600 personnel, which was a large portion of the small 1,600-strong permanent force.[4] AIC members wore distinctive uniforms, with unique embellishments and badges of rank. Members were posted to units across Australia, filling various roles including acting as the adjutant or regimental sergeant major in many Citizen Force units, and were tasked with running promotion, qualification and specialisation courses for citizen soldiers and with administering school cadet units
