a soldier does not have to follow an unlawful order. the problem is he must be willing to fight what will inevitably be the consequences of refusing to obey the order. the military doesn't like non compliance and they have a nasty way of showing it.
i was never in a combat situation so i can't know how i would react.
i was ordered once to sign a security cleearance and refused the order.
when i was called into a meeting of brass and given the a direct order, i signed it "under direct order."
they didn't like that but too bad.
i was the recipient of more then half dozen article 15's, company punishment, almost all for demonstrating my complete lack of respect for any one of rank that i thought was an ass hole. incidentally i was an e-2 so everyone else outranked me.
all my article 15's were for insubordination.
if i was at my lai, i hope i would have told whoever gave the order to shove it. i do know i would never respond to any order to kill unarmed civilians.
the reason soldiers come home with mental problems, PTSD, shell shock, whatever they called it at the time is very simple.
we are taught to respect other people and not to kill. when we are put in a position where we have to kill or be killed, even though we kill for self preservation, it is so stressful to our psyche, most people can not deal with it.
one day you are graduating high school and the next thing you know you are in a position to kill people.
how anyone can handle that is beyond my comprehension.
