During the exercise South Korea will focus on peacekeeping operations including disaster control, according to local officials.
Six nations are participating in the CG exercise including the US, Japan and Singapore, which will also deploy an amphibious vessel and several armoured landing vehicles.
A total of nine countries including the UK, Canada, India and Mongolia will attend the forthcoming exercise as observers.
