在朝鮮アメリカ陸軍司令部軍政庁
After Korea was liberated from the Empire of Japan on August 15, 1945, the Korean Constabulary and the Korean Coast Guard (organized by Sohn Won-yil and others) were established through the United States Army Military Government in Korea. The Korean Constabulary and the Korean Coast Guard became the Republic of Korea Army and Republic of Korea Navy respectively, and formed the Republic of Korea Armed Forces after the South Korean government was established on August 15, 1948. The Republic of Korea Air Force was founded in October 1949.
