Ii was just about this time in 1970 when we invaded Cambodia. And military hostile invasions being what they are there was a lot of things going on. Artillery, tanks, F4s, helicopters, trucks, infantry and everybody mad about something. I was on a tank, we were moving up and came out of the woods onto a large pineapple field. Right in the middle of it was a Cobra gunship just sitting there with the blades slowly turning. Got a little closer saw and the pilot and gunner standing in the shade of the helicopter, both taking a leak and smoking a cigarette. They waved, we waved, we went on down the road, few minutes later they flew over us going back to whatever they were supposed to be doing.
