He was among six recruits who excelled in various categories of their training. After becoming a member of Tinjojela, Prince Mandlesizwe performed a Zulu traditional dance with his colleagues. It could not be ascertained if Prince Mandlesizwe would be based in Swaziland or not after his graduation.
