Military snipers from the US, UK and other countries that adopt their military doctrine are typically deployed in two-man sniper teams consisting of a shooter and a spotter. A common practice is for a shooter and a spotter to take turns in order to avoid eye fatigue. In most recent combat operations occurring in large densely populated towns, such as Fallujah, Iraq, two teams would be deployed together to increase their security and effectiveness in an urban environment. A sniper team would be armed with a long-range weapon and a rapid-firing shorter-ranged weapon in case of close quarter combat.
