I think the ending of the tiger is an open ending, with only gunshots at the end. I'm not sure whether Mueller was killed by a child soldier or a child soldier was killed by mold.

But in any case, the ending is not good.

It's a pity that the child soldier is a loyal soldier, but he is too fanatical. Muller loves soldiers like children (every time a baby soldier calls his teammates deserters and sends Hartman out for reconnaissance, Muller is angry and sad, and the baby soldier is also brought up by Muller). Seeing that the country had given up on itself, he decided to surrender.

In fact, child soldiers are not extremely fanatical. Repeating slogans and accusing teammates is actually a kind of self-deception and self-comfort when the country is about to die.
