I'm wondering how that type of encounter would turn out in real life. I suspect it would have been a lot simpler and over very quickly; either Sam would have been down irreparably or Callan would have put some rounds into the Ghorkas pelvis at least. Also, Ghorkas are good shots, and I'm sure one working as an agent for Indian intelligence go go around attracting unwanted attention by leaving heads here and there by using just his khukuri. OTOH, I was kinda disappointed there was some more khuk work...
