KATUSA

 KATUSA stands for Korean Augmentation To the United States Army. Qualified Korean draftees who demonstrate a high level of English fluency and aptitude via a standardized written exam (usually the TOEIC) may apply for a KATUSA slot. Conscripts with qualifying test scores are selected on a random basis via lottery by the Korean government. Once selected, KATUSAs must complete six-weeks of ROK Army basic training. A brief orientation and OJT is conducted by the U.S. Army before they begin their full-time duty with a United States Army unit garrisoned in Korea for the duration of their military service.
 The number of candidates vying for an available opening is extremely high because many soldiers believe that the U.S. Army is less abusive and more professional in its training and treatment of soldiers compared with the ROK Army, and that junior enlisted personnel receive better treatment, have more educational opportunities (especially with regards to learning English), experience a higher standard of living, and have an overall better quality of life than their ROK counterparts. Many also believe that serving as a KATUSA engenders more respect from other Koreans, compared to their counterparts in the South Korean military. In 2012, roughly 3,400 KATUSA soldiers served with 25,000 USFK, versus 4,800 in 2005 and 11,000 in 1968. As the number of U.S. Soldiers in South Korea decreases, the number of KATUSA soldiers is decreasing as well. The ratio of U.S soldiers to KATUSA soldiers is roughly and informally 10:1.
 I'm planning to apply for KATUSA after taking TOEIC test this July.
