In the period 1945–93 the RAOC, as with the rest of the Army, reduced greatly in size and closed its worldwide bases as garrisons withdrew. At the same time, there was considerable development of warehousing techniques and information technology (the first move towards computerisation came with the opening of an Automated Data Processing Installation at Chilwell in 1963 and one at Bicester the following year.) In the mid-1960s new recruits were informed that 'The RAOC occupies nearly 90 different locations in the UK alone and world wide uses 86,000,000 square feet of storage space. Over 1,000,000 different items are held in stock and over 11,000,000 issues are made in a year'. By 1980 the RAOC was reduced to two CODs at Bicester and Donnington (COD Chilwell was closing, CODs Branston and Didcot had closed in 1963 and Weedon in 1965 after being downgraded from a COD in 1957), two CADs at Kineton and Longtown (Nesscliffe had closed in 1959, Corsham in 1963 and Bramley in 1974) and three Central Vehicle Depots: Ludgershall for 'A' (armoured) vehicles, and Ashchurch and Hilton for 'B' ('soft-skinned') vehicles (CVD Marchington having closed in 1965, CVDs Feltham and Irvine in the early 1970s).
