1) Were they doing something others weren't, or ISAF isn't; or

2) Were the conditions (poor opponent, terrain, ROE, etc) that led to the RLI's apparent operational success something that can't be replicated in Afghanistan; or

3) Are the contact and kill rates claimed for the RLI accurate.

As far as I can see, those are the three logical possibilities--and working out which apply is the purpose of the thread.
Rex: These are the million-dollar questions. Let me try to investigate the RLI and Zimbabwe and find out.
