President Yoon Suk Yeol visited a front-line military unit Tuesday to encourage soldiers serving during the Chuseok fall harvest holiday, according to his office.

Yoon visited a border unit of the 15th Infantry Division, where he pledged full support to ensure that soldiers could take pride in their service, presidential spokesperson Jeong Hye-jeon said.

"I will do my best as the commander-in-chief to improve your working conditions so that you can focus on your duties without worry and feel proud to wear the military uniform," Yoon was quoted by Jeong as saying.

Yoon emphasized the importance of maintaining a strong state of readiness in response to increasing threats from North Korea amid the recent sending of balloons filled with trash across the border and GPS jamming attacks.

Yoon also highlighted the 15th Division's critical role in a key battle in Gangwon Province during the 1950-53 Korean War, noting that he feels reassured by the unit's current state of readiness.

During the visit, Yoon took a photo with approximately 500 soldiers, including RM of the K-pop supergroup BTS. RM, who enlisted in December of last year, is currently serving with the division's military band. (Yonhap)
