News of Harrison’s success comes amid concern over a rival insurgent sharpshooter who in a five-month spree has killed up to seven British soldiers, including a sniper, in and around the Taliban stronghold of Sangin.
Sounds ominous. Apart from Valin's first link on the subject that mentioned an enemy 'sniper' being killed by a Jav, I haven't heard anything about the Taleban fielding snipers. To the contrary, all open source reports seem to indicate that the competent marksman is an exception amongst the insurgents. Hopefully the report is either erroneous or mistaken.
