About 20 military personnel from the U.S. forces in South Korea will assist South Korean troops in next week's exercise, the first such maneuver since last month's incident, Yonhap reported.
Members of the Military Armistice Commission of the U.S.-led United Nations Command will observe the one-day drill.
"This is a routine training and it is a routine observation that the United Nations Command provide to ensure the armistice compliance," said Col. Kurt Taylor, the command's secretary.
Taylor said the command has observed the South Korean military's trainings on a regular basis and the "armistice agreement applies to all territory in Korea of land, sea and air."
"The exact timing of the drill will be fixed later after considering weather and other relevant conditions," said Col. Lee Bung-woo, spokesman for the Joint Chiefs of Staff.
Just days after the Nov. 23 attack by North Korea, South Korea and the United States staged four days of large-scale naval drills in the Yellow Sea with a nuclear-power U.S. aircraft carrier taking part.
