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 AVLB bridge-laying vehicle on the way to the base camp after a training exercise accidentally killed two girls.
