Hi David,
As far as the threat envelope is concerned, it appears to be quite similar: mines/IEDs, RPGs, occasional anti-armour, etc. The designs should work, as would some of the Israeli designs.
The only problem with the South African versions is that they suffer from a fatal flaw: "Not designed here in the good ol' USA" . Which means that some congressman doesn't get to claim they got their constituents a juicy contract to research something that has already been designed.
