when drinking at a party. i asked a marine if he would be lee harvey oswald(in the offical story) if ordered to do so. he said he follows his orders with a glassy look in his eyes. he didnt say any more this was years ago long before trump was president. in oposition to that. a more light hearted individual i worked with that was in the army said in a concerned voice: "how do you shoot women and children." then with a smile "you lead them more". it was a little chilling. A different vetern would say "were here to blow shit up" we were never there to blow shit up when he said it. Another former ranger brother of a friend sent me around the garage to head off the "enemy" I expected him to hit me on the other side but in fact he just had a small flash black hallucination and thought there was a thief behind the garage and trusted me to back him up if a fight insued. three others were in the navy and seemed unaffected by their service.
