A status of forces agreement (SOFA) is an agreement between a host country and a foreign nation stationing military forces in that country. SOFAs are often included, along with other types of military agreements, as part of a comprehensive security arrangement. A SOFA does not constitute a security arrangement; it establishes the rights and privileges of foreign personnel present in a host country in support of the larger security arrangement. Under international law a status of forces agreement differs from military occupation. Agreements While the United States military has the largest foreign presence and therefore accounts for most SOFAs, the United Kingdom, France, Australia, Germany, Italy, Russia, Spain, and many other nations also station military forces abroad and negotiate SOFAs with their host countries. In the past, the Soviet Union had SOFAs with most of its satellite states. While most of the United States' SOFAs are public, some remain classified. NATO has its own procedure that stems from "a peacetime agreement originally signed in 1951" for SOFAs between member states. Terms of operation A SOFA is intended to clarify the terms under which the foreign military is allowed to operate. Typically, purely military operational issues such as the locations of bases and access to facilities are covered by separate agreements. A SOFA is more concerned with the legal issues associated with military individuals and property. This may include issues such as entry and exit into the country, tax liabilities, postal services, or employment terms for host-country nationals, but the most contentious issues are civil and criminal jurisdiction over bases and personnel. For civil matters, SOFAs provide for how civil damages caused by the forces will be determined and paid. Criminal issues vary, but the typical provision in U.S. SOFAs is that U.S. courts will have jurisdiction over crimes committed either by a servicemember against another servicemember or by a servicemember as part of his or her military duty, but the host nation retains jurisdiction over other crimes. Host nation concerns In many host nations, especially those with a large foreign military presence such as South Korea and Japan, the SOFA can become a major political issue following crimes allegedly committed by servicemembers. This is especially true when the incidents involve crimes such as robbery, murder, manslaughter or sex crimes, especially when the charge is defined differently in the two nations. For example, in 2002 in South Korea, a U.S. military
