The picture was taken in Oct, 1967 during an EXTENDED 40 day mission for 3 LRRP tms from the 1/101st (they were really a LRP co then but they still called themselves the 101st LRRPS) this was their Firebase they built on hill 803 (?) west of Chu Lai.
SGT Gregory "Dirty Ernie" Winston is seen with his sawed-off shotgun guiding in a SLICK with a 50 CAL on board so they would have a little more firepower. Ernie would receive his 10th Purple Heart later on that mission and his 13th Purple Heart when he was KIA in Jun 1968 when he was with the TIGER FORCE.
