From Kulak:

The Taliban it seems are really bad shots. Of the 93 enemy sniper ops included in the Afghanistan data set 67 resulted in no Casualties at all, the insurgents or Taliban simply rode up on a motorcycle to some range, fired 1 or 2 shots that missed, and rode away. Of the remaining 26, 6 resulted in only enemy casualties, with the remaining 20 being something of a mess of friendly wounded and enemy casualties, in only one incident is a coalition fighter, a member of the 1st Royal Anglian, killed by sniper fire, and in two incidents are Friendly host nation forces killed, only one of which looks like a traditional sniper attack (the other is a messy assault that really stretches the definition).
