the Olympic Games (SOCOG) under "Operation Gold". Known as the Operational Search Company their duties included conducting area searches, building searches and manning vehicle checkpoints. Whilst full-time leadership and increased readiness had their benefits, increased time requirements for individual training for recruit and promotion courses contributed to a decline in Unit strength over the 2001/2002 period. The role of the Army Reserve was changing and so was 5/6 RVR in response to those changes. A dedicated staff of Reservists and full-time members continued to work to provide the expertise and staffing required to train and develop young and upcoming 5/6 RVR soldiers. In early 2003, the Reserve Response Force (RRF) concept was being rolled out to 4th Brigade. 5/6 RVR was chosen to lead the first Reserve based 4th Brigade RRF. The RRF role was then devolved to unit level and 5/6 RVR continued to strengthen its role through Bravo Company, the largest Company, which was chosen to lead the battalion's RRF elements. The Sesquicentenary – 150th anniversary In 2004 5/6 RVR celebrated its Sesquicentenary – or 150th anniversary. A "Sesquicentenary Committee" was formed chaired by the Commanding Officer, LT COL Mark Richards. The committee was functionally led by Battalion 2IC MAJ Terry Kanellos and included current and past members of the battalion and networked extensively with the help of MAJ GEN James Barry, MAJ GEN Greg Garde and the then Regimental Colonel, COL Paul Riley. A number of activities and functions were planned throughout the year involving all ranks. The year began with a series of Unit History presentations given throughout the battalion by Company personnel. Working with the support of Battalion Associations, the committee planned and conducted the following activities: An All Ranks Reception at Government House hosted by his Excellency, Mr John Landy AO, Governor of Victoria on 17 September 2004; A Freedom of the City of Melbourne march on 16 October 2004; Gala Ball – The Atrium Room Flemington Racecourse on 16 October 2004; An Employer Function – Hosted and sponsored by Mr & Mrs Dick and Jeanne Pratt at their Raheen Residence in Kew, Victoria on 25 November 2004; and An End of Year Battalion Christmas Party at the Telstra Dome on 11 December 2004. The year also saw an increasing focus on the Battalion's role in 4 Brigade's Reserve Response Force (RRF), with an emphasis on training and individual preparedness. Urban tactical training and
