This is the map we used to plot incoming rockets
(from the information supplied by the Security
Police on the three (3) rocket towers on TSN.)
They would give us the coordinates of the flash
and we would pull the strings across the map and
give ARMY the triangulation.  Then ARMY would
dispatch a welcome committee of Cobra choppers.
