Smith had been dropped off to man a solitary observation post, but dense fog prevented him not only from doing the job he was supposed to do, but also meant that the helicopter that was to rescue him wasn’t coming.
Dropped off at the LP OP by helo, check.
Fog stops you from doing your job, check.
In need of "rescue"? How did we go from being at an observation post to rescue?
And how long did that fog last? Weeks?
Poor John Smith was bounced from camp to camp with no help in sight. A baseless green beret that no one loved. I wonder if he stood at the trails edge with a sign,
"Baseless, please help. Vietnam Veteran."
