Condolences to the friends and families of these ROK soldiers killed in this helicopter crash.  Judging by the below picture it looks like it crashed right outside the wall of the military base:

A South Korean military helicopter crashed in an eastern province on Monday, killing three of the four soldiers on board, officials said.

The helicopter went down in a farming field in the city of Chuncheon in the eastern province of Gangwon during a checkout flight, defense and army officials said.

The officials said that all four soldiers aboard the helicopter were initially rescued after the crash, but that three of them died while being treated in hospitals.

They said no casualties on the ground have been reported. The cause of the crash is under investigation.  [Washington Post via a reader tip]
