Two more members of K-pop phenomenon BTS, RM and V, were set to start mandatory South Korean military service on Monday (Dec 11), local media reported.
The remaining two members, Jimin and Jungkook, are expected to enlist on Tuesday.
All able-bodied men in South Korea must serve at least 18 months in the military.
After a years-long debate about whether BTS deserved an exemption, Jin, the oldest member of the group, enlisted last year and his bandmates J-Hope and Suga followed this year.
RM and V were set to begin their five-week basic training at an army boot camp in South Chungcheong province on Monday, the Yonhap news agency reported.
RM – whose full name is Kim Nam-joon and is the leader of BTS – posted a message to fans late Sunday, saying it will be “a time of learning and new inspirations”.
“Goodbye for now. Let us be us, whenever and wherever! Let’s meet in the future,” he wrote on social media platform Weverse.
