That is the riot squad.  You must understand the difference between the riot squad and the security branch.  The security branch are people who were members of the security and riot squad are members of the uniformed police so I've included him as a member of the riot squad and some of them were special constables.
	The objective of the riot squad and special constables was to barr the violence or riots in the townships, some of them were just mentioned as special constables but they were senior, so he was not a member of the security branch.
