Looks like the platoon Cpl/Sgt is pointing out to the sniper a position that is causing them problems. I'd just use the section artillery - the 2" mortar - to do it. That gets 'em all. Rifle is a No4T trials. Looks like the scope is in a mk2 case around his back. Anyone recognise the tactical sign on the snipers arm. These were usually obscured by the censor.
