问：if president order military to shoot protesting civilian? can Military soldier reject the order?
答：
Yes, a soldier can and is legally obligated to refuse a presidential order to shoot protesting civilians if the order is deemed "manifestly illegal" and a clear violation of the Constitution or human rights
. The Uniform Code of Military Justice requires service members to obey lawful orders but disobey unlawful ones. While disobeying a lawful order carries risks, refusing a manifestly illegal order, such as targeting civilians, is not only permissible but legally required.
