Read the book, Asher does have a position from the start of the book but the programme didn't really reflect the book too well. If he didn't have a position then he wouldn't have written the book and of course the book was written after the trip and the research therefore it would be difficult not to have a viewpoint.
Having been in a shooting situation I can assure those who haven't that it is as much luck as judgement to hit someone when they are trying to blow your fat head off as well. The real world is not scripted by Audey Murphy.
Look at the total land casualties caused by the British Army with several thousand trained infantry in the Falklands then compare it with the claim of 250 casualties caused by eight guys from B20 who by their own admission were in no state to even control some of their body finctions within 12 hours of the do do hitting the fan. If they had been carrying 1,000 rounds each then they would still have had an extraordinary hit rate.
Me smell a rat, but for the money these guys made I would lie through my teeth and camp the whole thing up as well.
