Watch | South Korean soldiers change boots for ballet slippers

South Korean soldiers deployed near the border with the North take ballet lessons as part of their training. The soldiers say it helps with flexibility and strengthens the muscles. Teacher Lee Hyang-jo, who dances with the Korean National Ballet, says it's a rewarding job. The soldiers are staging a ballet at the end of this year and hope to top last year's performance of part of Tchaikovsky's Swan Lake.
