15 Reception Depot  15 Reception Depot was an administrative unit of the Personnel Service Corps of the South African Army.  15 Reception Depot (15 RCD) was activated on 10 September 1939 to muster South African volunteers signing up to take part in World War 2, it operated as the reception depot to service the then Witwatersrand Command. The depot drew its recruits mainly from Johannesburg and the immediate surrounds. The depot operated from the Milner Park Showgrounds and the Wanderers Grounds in Johannesburg. 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. . The unit was reactivated on 29 April 1964 owing to the threat of a United Nations action in respect of South West Africa, and in case such a situation required the mobilisation of South African Army Citizen Force units. 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. Men of ‘black’ South African heritage at the time were recruited into the South African Army on a voluntary basis and joined ethnically differentiated Battalions directly as 'Permanent Force' members.  15 Reception Depot was one of a number of Reception Depots around South Africa which was tasked to the intake of national service conscripts into the South African Defence Force (SADF). Each Regional Command in the SADF structure had its own Reception Depot. Due to the population size of the Witwatersrand region and resultant intake size, 15 RCD spearheaded the drafting process. 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. The explosion injured 26 people (a mix of both military personnel and by-standing civilians) with no deaths, the building was however deemed unsafe and 15 Reception Depot's HQ moved into a high rise building adjacent to the Drill Hall.  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.
