Goof....
...when Lauderdale and Wilkes are making their way around to attack the gun placement. They're crouching down in hiding from a kitchen worker and when they turn to leave, you can see a sound boom reflected in the hut window.
Another 2 noticed:
a. the RSM continues to wear his Sam Browne belt in the mess at dinner. Sam Brownes, likr head dress, are removed upon entering a mess;
b. the fictional regiment has taken the light infantry bugle horn as their cap badge and collar dogs. Normally, these are worn with the mouthpiece facing in and not the reverse as they do in this fil.
Otherwise, great film.
