During the Afghan wars of the 'Great Game' tribesmen would hide in the crevices of the rocky mountainsides to observe and to shoot at the British soldiers. These would shoot back, so the positions would be fortified with slabs of rock, embrasures, roofs, camouflage. The Afghan word for these tiny little forts is Sangar. Things have not changed much, and a Sangar is an OP which is protected against incoming ordnance and the weather, and from which weapons as well as binoculars could be used. A Sangar is a fortified OP. Often a Sangar will be equipped with a Mortar Roof, a Rocket Screen and Cover From View.
