Irrespective of whom,what ,when, where, anyone joining the military should be aware:- You are paid to take orders from the heirarchy above you, no ifs ands or buts... kill or be killed, that's the objective of your employment -group.
It's non-negotiable, Military = obay orders to kill whoever your superiors dictate..........if you didn't think that one through before you signed up for the glamour/excitement/prestige/travel/cush number...or one of the myriad of other excuses I've hearrrr fo joining a killing-machine.....no sympathy, tough cheddar.
