Factual error: When the bird Charles shoots lands on the land mine, you can see thing bounce on one side of the explosion. If the bird had really landed on the mine, it would have been obliterated.
Suggested correction: Anti personnel mines are specifically designed to badly wound someone rather than kill them outright, as it takes more people to deal with a wounded casualty rather than if they were dead. Movies exaggerate the blast effect as anti-personnel mines don't actually blow anyone to pieces, even a large bird.
True, but in this instance, it was a small bird. The mine in question can severely maim or destroy limbs, therefore the bird shouldn't have been seen.
