South Korea and the United States will launch their largest-ever joint exercise this week to warn North Korea against further provocations, Yonhap quoted a South Korean military official as saying Sunday.

The Key Resolve and Foal Eagle exercises running from Monday through April 30 will be the largest in scale since Pyongyang's torpedo attack on the South Korean corvette Cheonan in 2010, which is what originally triggered these annual drills, the official said on the condition of anonymity.

This year's exercise will involve more than 300,000 South Korean and 15,000 U.S. troops and simulate previously unattempted strategies.

The Key Resolve portion of the exercise will include OPLAN 5015, which aims to remove the North's weapons of mass destruction and prepare the allied troops for a pre-emptive strike in the event of a North Korean attack.
