While the U.S. military has the largest presence abroad, making it most SOFAs, the United Kingdom, France, Australia, Germany Italy, Russia, Spain and many other nations also deploy military personnel abroad and negotiate SOFAs with their host countries. In the past, the Soviet Union had SOFS with most of its satellite states. While most SOFS in the United States are public, some remain classified.  The Status of the Armed Forces Agreement (SOFA) is an agreement between a host country and a foreign nation that deploys military forces in that country. CANPAÉs are often included with other types of military agreements as part of a comprehensive security agreement. A CANAPÉ is not a safety device; it establishes the rights and privileges of foreign staff in a host country in order to support the greater security regime.  Under international law, a force status agreement differs from military occupation. The parties to the North Atlantic Treaty, signed in Washington on April 4, 1949, considering that the forces of one party may be deployed on the territory of another contracting party after consultation; Knowing that the decision on their deployment and the conditions under which they are communicated, if these conditions are not specified in this agreement, will continue to be the subject of separate agreements between the parties concerned; to define the situation of these forces on the territory of another party; Agreed as follows: The political issue of SOFA is complicated by the fact that many host countries have mixed feelings about foreign bases on their soil, and calls for a renegotiated NEW SOFA are often combined with calls for a total withdrawal of foreign troops.
Issues of different national practices may arise – while the United States and host countries in general agree on what constitutes a crime, many American observers believe that the host country`s judicial systems offer much lower protection than the United States and that the host country`s courts may be under pressure from the public to be found guilty; In addition, U.S. service members who are invited to send shipments abroad should not be forced to waive their rights under the Rights Act. On the other hand, observers of the host country who do not have a local equivalent of the law of rights often feel that these are irrelevant excuses for special treatment and resemble the extraterritorial agreements demanded by Western countries during colonialism. A host country where such sentiment is widespread, South Korea, itself has forces in Kyrgyzstan and has negotiated a SOFA that gives its members total immunity from prosecution by the Kyrgyz authorities for any crime, which goes far beyond the privileges that many South Koreans enter into their country`s couch with the United States.  An agreement on visiting missions is akin to an agreement on the status of the armed forces, with the exception of the first, which covers only troops temporarily stationed in a country that does not reside there. A sofa should clarify the conditions under which the foreign army can operate. As a general rule, purely military issues, such as base location and access to facilities, are covered by separate agreements. A SOFA focuses more on legal issues related to military individuals and property.
This may include issues such as entry and exit, tax obligations, postal services or the employment conditions of nationals of the host country, but the most controversial issues are the civil and criminal competences of bases and staff.
