Like most military forces in the world, the South Korean military has different branches or divisions: the Army (ROKA), the navy (ROKN), the Air force (ROKAF) and the Marine Corps (ROKMC). There is also the reserve forces. Near the demilitarized zone in the North Korean border, these forces are mostly concentrated. The military is so important that all males are required to serve for two years. Some Koreans believe that the 2 years mandatory service should be shortened or even completely abolished. The government has actually allowed some male students who were about to graduate with a bachelor’s degree and with a master’s degree to skip the 2-year military service so that they could focus on their studies and further their knowledge on their chosen specialization.
