Every year in Thailand, men in qualifying ages are demanded to take part in the military lottery. A man who picks a black ball is exempt from the military service. On the other hand, a man who picks a red ball is required to enlist within a year for a 24-month mandatory service.

On April 1, TEN, a Thai idol, traveled back to his homeland to participate in the lottery. However, even before the lottery, he was exempt due to his failure to pass the physical exam. His past injury and surgery on the knee were deemed unfit for mandatory service. As a result, TEN is officially exempt from service and he doesn't have to leave his idol career to serve his country. 

Meanwhile, GOT7's BamBam, also a Thai idol, will be taking part in the military lottery in the near future.
