The ROE for some missions in Vietnam allowed for killing anyone who might interfere with the mission, or compromise the safety of the detachment involved. Reference (among others) the actions of Lt. (later Senator) Bob Kerrey and his SEAL Team at Thanh Phong, RVN, Feb., 1969. (This is the incident one of Kerrey's men described very differently from Kerrey's account years later-other members of the detachment seem to remember it differently). In any case, I would not question the decisions Kerrey made, or the orders he gave, one way or the other; I have no way of knowing exactly what he heard and/or saw. However, in a similar situation as that described, I might well have done the same, under the same ROE. The "civilians" they killed were likely VC sympathizers. This was not out of the ordinary, nor is it anything most of us at the time would have lost any sleep over. Kerrey reported the incident; it was determined at the time that he acted within the scope of his orders and the ROE. Kerrey remarked years later that he did not recall any lectures on the Laws of War; I would say that was fairly typical for officers at that time. I cannot remember the subject ever being discussed, nor do I recall any superior ever telling us to "be compassionate". The label "free fire zone" meant any Vietnamese encountered therein was presumed hostile, and could be engaged should a commander feel they were a threat. That judgment was rarely questioned. The usual advice was "use your own discretion". There was no requirement that we "prove they were hostile"; it would have been up to whoever questioned the action to "prove" they were not. In plain language, if we were compromised, it was generally permissible to waste whatever or whoever was doing the "compromising"-problem solved. If you insist on knowing whether I personally gave a damn, then or since, the answer is "NO!" I never felt compelled to kill anyone who was not armed, but had I found that necessary, I would have done so. Different war, different time, different mindset, different training. The way you were trained is a direct result. We can argue all day over whether it is a good result, or an unfortunate one, but it is current military policy. So far as I am concerned, I believe that policy and the accompanying training to that effect is politically motivated. You and the modern army may not approve of the way we "throat slitters" operated in Vietnam, but I will tell you that militarily, it worked, and to me, that is the only thing that matters.
