Make up of the South African Army?

Hi Indy! Been following your channels for years and i really appreciate what you do especially in these times. Anyways, i was wondering if you could tell us about South Africa and its military during the war. Reaction of parliament and people to the war? State of the army in 1939? The racial make up of the army or race requirements? Combat and casualties up until this point in the war etc? Cheers guys.
