Do you think troops are immune from fake news? The reality is, if SHTF the military is gonna split between the indoctrinated, those willing to bend the knee for 30 pieces of silver (the safety of their family, guaranteed resources in a time of need), and the patriotic. Command will lean towards the first two. Better to be pleasantly surprised than to take a hubris stake to the heart realizing DoD isn't any different from the others when it's far too late.
