 Attack footage is more graphic. When people are blown out of sand bag   barricades instead of whole bodies you see bloody limbs and torsos go   flying. Also during the films many strafing scenes we now see huge chunks   of meat and body parts being blown off the falling people. If you look   closely during the "nurse strafing" scene, when Evelyn and Sandra are   ducking down by the fountain, you can even see a man get cut in half by the   20mm rounds coming from the strafing Zeros.
