15 Reception Depot was an administrative unit of the Personnel Service Corps of the South African Army.

The unit was also responsible for the routing and demobilisation of returning South African Union Defence Force (UDF) soldiers until it was disbanded after the Second World War on 31 December 1945.

When the threat subsided, the unit was retained to process the bi-annual national service intake of white South African conscripts drawn from the greater Witwatersrand area.

The government policy of compulsory conscription preceding 1994 was exclusively for young ‘white’ South African men.

The reception depot units fell under the Personnel Services Corps (PSC) of the SADF.

To mobilise these 'white' South African conscripted troops, duties and tasks performed by 15 RCD involved: 15 Reception Depot HQ was stationed at the Witwatersrand Command's Drill Hall in downtown Johannesburg until the Drill Hall was bombed on 30 July 1987 by a lone Umkhonto we Sizwe insurgent, Hein Grosskopf.

15 Reception Depot initially conducted the bi-annual intake of national servicemen from Sturrock Park railway station in Johannesburg and escorted these recruits to their respective army training units by train, this intake of conscripts was later moved to the Nasrec Expo centre show grounds and the majority of national servicemen recruits were convoyed to their training units in busses.

By the early 2000s, Commands were no longer responsible for individual recruitment, making Reception Depots essentially redundant.
