It is not known if the U.S. Military uses snipers in Iraq. However, it is very likely that the the Unites States Military uses snipers in Iraq. The government or the military it self don't tend to release information often.
One that you can not touch and be around does that answer your question Not sure what that answer means. It depends: most snipers use a large caliber sniper rifle of some kind, but not every one uses exactly the same rifle. Most major manufacturers make some sort of sniper version of the rifle.

Yes because snipers can kill from distances. The shotgun is the close combat weapon because it is only stronger in closer range but the sniper rifle can kill really far away. Snipers are trained to be invisible but not the shotgun. Today most military soldiers are now using the sniper rifle better than the shotgun. Snipers have perfect penatrations of firing against body armors but the shotgun has a poor penatration of firing through the body armor. Snipers are much more better than shotguns because snipers are much more powerful than shotguns and they can kill without being spotted by their enemies. So the sniper rifle is the winner. Actually, it depends on the intended use. The original question was too vague to assume it was meant they way you answered it. At close distances, a shotgun is typically a better choice.
Military personnel, such as scouts or snipers, regularly camoflague themselves to avoid being seen. They may use strips of fabric to break up the distinctive shape of a rifle. This is usually a coarse fabric such as jute or burlap, cut into irregular strips, and wound LOOSELY around the rifle.
