Korean boy-band BTS, the best-selling group in South Korean history, are soon to commit to their mandatory military service.

South Korea requires all able-bodied men aged between 18 - 28 commit to military service. The service lasts between 18 - 24 months.

Exemptions are made for athletes, classical and traditional musicians and dancers who have won top prizes in competitions which boost the prestige of the country.

Tottenham Hotspur footballer Son Heung-min gained exemption after winning gold in the Asian Games in 2018. He took part in six-weeks basic training during the summer.

In 2020, new legislation allowed K-Pop groups like BTS to delay their service up to the age of 30. There has been ongoing discussions on whether to make exemptions for K-Pop stars given their international appeal.

However, the group announced this week that they are "moving forward" with proceedings and will be taking a break as a band until their service is complete.

The statement, released by management company BigHit Music, said the members were "honoured to serve".

"Both the company and the members of BTS are looking forward to reconvening as a group again around 2025 following their service commitment."

The oldest member Jin, 29, will begin his service at the end of the month. The rest will then follow "based on their own individual plans."

Made up of seven members, Jin, RM, J-Hope, Suga, Jimin, V and Jungkook, BTS are the first non-English-speaking and Asian act to hold sold-out concerts at Wembley Stadium and the Rose Bowl.

The group's many accolades include multiple American Music Awards, Billboard Music Awards, Golden Disc Awards, and nominations for two Grammys.
