5 SA Infantry Battalion Flags

5 SAI was established on 1 January 1962, at Ladysmith, Natal Province. The battalion became operational on 1 April 1962.

5 SAI had a very unusual proficiency in the 1970s and 1980s, called the Insizwa, the Zulu word for a strong young man. The criteria required that only sharpshooters on a tabel 4 level were allowed to compete. A 2.4 kilometres (1.5 mi) run had to be done under ten mins with battle kit on, followed by 20 kilometres (12 mi) route march also with battle kit. The route march would end at the 200 metres (220 yd) firing line where the competitor would have to shoot 8 shots in the bull. The soldier would also have to successfully complete all other shooting exercises with an 80% success rate. Wikipedia
