The second volume, entitled ‘SIGNAL UNITS OF THE SOUTH AFRICA CORPS OF SIGNALS AND RELATED SIGNAL SERVICES’ represents one of the most comprehensive collection of regimental and unit histories ever published in one volume in South Africa. It is also the first time that the histories of many of the signal regiments and other units will be published and available to the general public, and will most probably – together with its two companion volumes - prove to be the book of reference on army signals in South Africa.
