Factual error: The G.I.s are an army unit, but are wearing United States Marine Corps uniforms.
Continuity mistake: Sgt. Killian is wearing his helmet, but when the North Korean soldier kills him from behind, his helmet is on the ground.

Continuity mistake: The flowers Sgt. Killian places in his helmet's netting change from fresh to wilted several times as the scenes change.
Audio problem: The Sergeant is calling "Sunrise 6" on his radio hand mic, then tucks away the mic to scan the mountain with binoculars, but his voice is still calling Sunrise 6.

Visible crew/equipment: The shadow of the camera filming the scene is visible on the hood of the jeep as it rolls down the road.
