The John Chard Medal (Afrikaans: John Chard-medalje) was instituted with effect from 6 April 1952 to replace the Efficiency Medal and the Air Efficiency Award which was previously awarded to members of the Citizen Force between 1939 and 1952. 
John Chard Medal awarded to officers and men alike after 12 years voluntary service in the Citizen Force
This bronze medal was awarded to members of the Citizen Force, irrespective of rank, who had completed twelve years' long and efficient service. The qualifying service did not need necessarily be continuous.
The medal is of bronze and the designation and significance is the same as that of the John Chard Decoration.
Distinguishing insignia in silver are worn on the ribbon. A miniature anchor denotes that qualifying service was in the SA Navy, crossed swords in the SA Army and an eagle in the SA Air Force.
A member eligible to receive the John Chard Medal after 1 July 1975 could elect to receive the SADF Good Service Medal (Bronze) instead. The member was, however, thereafter restricted to the series chosen. This stipulation in the Government Gazette seems to contradict the option offered under the regulations for the award of the John Chard Decoration and the SADF Good Service Medal.
