The 23-member Capstone Group, mostly comprising recently promoted brigadier generals, flew to South Korea on Sunday for a four-day trip, the JCS said in a statement.

The U.S. officers are to visit the border village of Panmunjom and major South Korean and U.S. military units in the South, the statement said.

The U.S. military runs a six-week education program for newly promoted general-grade officers, called the Capstone Program, which includes overseas trips to South Korea, Thailand, Hong Kong and Australia, it said.
