Other mistake: The navy bombardment opens fire and there are huge explosions. When they attack from the ropes they walk at least 50 yards with no craters, just flame and smoke. Awfully big guns for no holes in the ground .

Directed by: Mel Gibson
Starring: Sam Worthington, Teresa Palmer, Andrew Garfield, Rachel Griffiths
Factual error: Throughout the battle scenes on the ridge, the machine gunners can be seen picking up the guns to fire on the move. While not impossible, not as painless as it is made to appear. The M1919 .30 caliber air cooled machine gun was light enough to carry. But for the gunner to hold an already hot barrel and continue firing would have been extremely painful without the issued heat retardant mitten or the barrel "hoop" w/ wooden handle. These fixes allowed the gun to be fired on the move and saved many from having their palms burned and scarred for life.

Suggested correction: They have barrel shrouds which dissipate the heat and allow a grip...they are not in contact with the barrel.
Captain Glover: All I saw was a skinny kid. I didn't know who you were. You've done more than any other man could've done in the service of his country. Now, I've never been more wrong about someone in my life, and I hope one day you can forgive me.
