The Honoris Crux Silver (Silver Cross of Honour), post-nominal letters HCS, is a military decoration for bravery which was instituted by the Republic of South Africa on 1 July 1975. It was awarded to members of the South African Defence Force for exceptional acts of bravery while in great danger. The Honoris Crux Silver was the third most senior in a set of four classes of Honoris Crux decorations, which together replaced the discontinued Honoris Crux of 1952.
