Current Events > To what extent are American soldiers allowed to use their weapons?

(+) Yeah! (+)

Let's say for instance, a soldier was given a mission to clear out an occupied hotel in enemy territory. Halfway into the territory, he runs into a child that is holding a very dangerous weapon, ready to kill the soldier. Does the soldier try and work with the child or does he have no other option but to kill him and move on with the mission due to time constraints? How do they decide? What if it was a group of children? Would the soldier try to attack them all if he was under a legitimate threat? Thanks.
