In the scene when the African soldiers raise the French tricolor over the Italian mountain top, the flag they use is polyester (i.e. a contemporary flag). World War II troops would have used a cotton flag.
When Abdelkader and Yassir carry the bodies of killed soldiers in a cart to bury them, Yassir rests his gun against the wheel. In the next shot, the gun falls to the ground from a completely different position.
