South Korea and the United States will carry out their annual joint military drills in a low key manner from next week, the military said Sunday, amid the ongoing reunions of families separated by the 1950-53 Korean War. The allies will hold the computer-based command post exercise, called Key Resolve, from Monday to March 6, involving about 10,000 South Korean and 5,200 American forces, with 1,100 coming from overseas U.S. bases.
