After the chopper is repaired, during the test flight several scenes of it flying are reused several times, and one scene of it flying in a curve low to the ground is even played in reverse.
Stock footage of the pilots from the right side of the chopper as they fly it was reused in nearly every flying scene, and was stock footage of the choppers in flight. It is especially telling when you notice that the closeup of the pilots always shows a window with a unique bullet hole it in, and even when that particular chopper is supposedly shot down and lost that chopper and window with a bullet hole shows up again.
The infantry squad depicted at the start of the film is armed almost entirely with M1 carbines except two guys with M1 Garand rifles and one with a BAR.
The soldier hit by Korean gunfire also carries a carbine which he appears to lose in the water. However, when the helicopter arrives, he's helped to the chopper along with an M1 Garand.
Later when the squad are attacked by the tank every one of them appears to armed with Garands.

Near the beginning F86s are called in to knock out a tank, but the footage of the plane dropping the napalm is of a F80 not a F86.
The heroic sea rescue was only possible because of the pilot they had already picked up being able to operate the winch. Yet the Sgt on the chopper had gear for going into the water. But why? The procedure as depicted in the film could only work with a fourth crew member who would not normally be present.
