Read the report. It's not a document I would cite of feel comfortable doing so.

See my response to this very debate here, in article I was asked to right for RUSI

Having now talked to lot of UK guys back from A'stan, I have to say I am very un-surprised at what they actually say, which is that personal weapons are really just for self defence and under 200m and what does the killing is platoon weapons/section weapons, like GPMG, LRR and Projected HE. In other words all the lessons from the past 60 years hold true.
