an effective means to screen friendly movement. This can be used either to pass through and escape, or to close in on and eliminate the enemy sniper. Ordinary soldiers can still do damage through smoke by firing randomly or on intuition, but snipers lose their precision advantage and are far less likely to hit anything with their much lower possible shot volume. A determined enemy, such as an emplaced heavy machine gun, will fire randomly through smoke, so this is a dangerous tactic. Weapons of opportunity may also provide a smoke screen, anything from igniting a car's gas tank, oil drum, or using fragmentation grenades to throw up debris and quickly break line of sight and concentration. Rush: Also known as "Close With And Destroy." If the squad is pinned down by sniper fire and taking casualties, the order may be given to rush the sniper's position. If the sniper is too far away for a direct rush, a "rush to cover" can also be used. The squad may take casualties, but with many moving targets and a slow-firing rifle, the losses are usually small compared to holding position and being slowly picked off. Pincer movement: If the sniper's position is known but direct retaliation is not possible, a pair of squads can move through concealment (preferably cover) and drive the sniper toward the group containing the targets. This decreases the chances that the sniper will find a stealthy, quick escape route. A pincer movement attack can be combined with artillery or mortar fire, so long as this is tightly coordinated, i.e. the target area covered by bombardment does not overlap with the movement of the counter-attacking troops. Even if bombardment does not kill or wound the sniper, it may flush them from cover. Basic sniper identification method The defenders monitor contact. As soon as contact is taken, the defenders try to make sure to take cover. If the defenders are on dismount, they try to make sure cover is the closest and most secure cover possible. If the defenders are mounted, they try to ensure all gunners reduce to "Chin strap defilade" where nothing is showing out of the vehicle but the chin and above. The defenders try to ensure the gunner has proper shielding. The defenders scan the area to locate the sniper's position. The defenders pop smoke to cover and conceal their position. The defenders designate the
