This is what the first guard posts looked like.  They were temporary.  Very temporary.  They had no communications between the posts.  Only the corner guard posts, probably five, had phones.  The rest of us sat in silence.

The photo was taken behind the bunker I was in every night during March 1969.  They were just starting construction of roads and buildings for the units being transferred to FLC. In the background is the last bunker in the line.  It had a radio. In front of us was the reservoir and beyond a Buddhist burial site, Highway 1, Red Beach, and Da Nang Bay.

Behind the bunker in the background another 100 yards or so was headquarters for FLC.  That's where I worked.  The Photo-Lab.
