The Steel Helmet

A hard-bitten, cynical veteran sergeant, the lone survivor of an ambushed patrol, joins up with a South Korean orphan, a black medic, a Japanese-American, a former conscientious objector, and other ragtag stragglers and leads them to an abandoned Buddhist temple. They resist the efforts of a captured North Korean major to divide them along ethnic lines and use their strategically important location to direct American artillery fire onto Communist positions.
