Dennis,
Yes, they were the Yellow Scarfs, they did quite a bit of work for us, but sometimes, they were a bit too enthusiastic. Like when we were in Cambodia and they flew over our Recon patrol base, thought somebody was shooting at them and destoyed it with WP, wounding 4 of our guys in the process. Fortunately, none of the guys were seriously wounded, and when they found out what they had done, came back and picked up the wounded when we had trouble trying to get a dustoff.
