The group is scheduled to return to South Korea later Tuesday after undertaking preparatory work on repairs needed within the complex.
Experts say South Korea and the United States need to hold regular drills to prepare their commanders, who change periodically, to work together smoothly in crisis situations and respond to North Korea's evolving military threats and other factors such as changes in the deployment of USA strategic assets.
