Other mistake: The exact same background shot of a Ventura bomber followed by two single-engine planes flying left to right is used three times during the film, twice at the beginning as they are planning the mission on the beach and then once at the end when the raid is over.
Other mistake: Early on, the Americans discuss the fact that the Japanese move at night and hide during the day. Yet, when Mucci's men, still on foot, are moving towards the camp, they encounter an enemy armored column, moving in daylight.
