Actor Jo In Sung had enlisted in the Air Force last month for his mandatory military service, leaving his fans worried over whether he was able to adapt to the tough military training. A photo of Jo In Sung in uniform was published on the Air Force official website soon after his enlistment with his fans mighty relieved to see their idol looking in good shape. But new reports have surfaced today that, although Jo In Sung looks fine in the photo, he has suffered greatly during the tough training regime and had already been hospitalized twice within a month. According to reports, the army places great emphasis (extra tough) on basic military training, especially when it comes to new recruits. You don't get any special treatment even if you are a well-known star. Although Jo In Sung is noticeably older than most of the recruits enlisted at the same time as him, he has to go through the same punishing training regime like them without any discounts. In addition, as a well-known star in Korea, Jo In Sung has to shoulder extra stress from the attention showered on him from his superiors and comrades. Because of the stress, Jo In Sung had to visit the hospital a few days after enlistment for treatment, after developing gastric ulcers. Shortly after recovering from that, Jo In Sung had to be hospitalized again for 3 days on 29th April after injuring his right shoulder during a routine training exercise. But the nightmare for Jo In Sung will be ending soon on 15th May as his basic military training schedule comes to a close at the Republic of Korea Air Force Education and Training Command. Jo In Sung will be moving to Osan Air Base on 18th May where he will serve out the remainder 25 months of national service with the military performers section (band, music, MC work, etc) under the Air Force Operations Command.
