I believe these troops were indeed carrying loaded M-16s. Rules of Engagement are such that they were not authorized to use their weapons under these circumstances.
(Old copy of ping list, forgive me if you're on this one after being asked to be removed...HJ)
Thanks, HiJinx. There are contradictory reports going around on this. I'm going to go with your report, unless and until we learn differently.
I also understand, from a report that quoted a NG Major, that the NG calls in BP when they spot aliens but otherwise they are allowed to defend themselves. I would take that to mean they could return fire if fired upon.
