Yep, I remember as if it was yesterday. Did my basics in the SA Army in 1991. Things that stood out for me: Lack of seep, guard duty, inspections, the smell of brasso and floor polish, PT, kak food, being chased around the parade ground and of course Sergeant Major (RSM) Venter. The Corporal would ask you to fetch a leaf on a tree on the far side of the parade ground, when you return with the leaf he says it is not the one he wants and you must run back and fetch another one. Another thing that stood out for me is doing PT with a tank track. IMHO, I think the Navy okes have it pretty easy.
One person you stay clear of is the base RSM (Regimental Seargeant Major). That guy could make your life a living hell. I saw a Lt.Col being chased off the RSM's parade ground by the RSM.
