RAUSI began as âThe Alberta Military Instituteâ on 14 May 1920. On 21 May 1947 it became âThe Alberta United Services Institute,â and finally, the prefix âRoyalâ was added by royal granting on 31 October 1975. Since 1920 the Institute has been housed at the Mewata Armoury in Calgary, sharing the Officersâ Mess with the various units stationed in Calgary.
Over the years RAUSI has provided funds for Reserves, Bursaries, Cadet Corps, upgrading the Mess facility, and Veterans groups, including the Poppy Fund Veteransâ Food Bank and the Colonel Belcher Care Facility, and the Military Museums. In addition, RAUSI has assisted with special commemorative services, and provides a library, together with the University of Calgary, now housed the Military Museums.
