Another great set of photos provided by Jamie Swidecki. By this time Delta Company was participating in actions in the infamous I Corp area, including Khe Sanh, and the A Shau Valley. Thanks for providing the photos Jamie.
Background with no helmet is Ed Johnson; he was platoon sergeant some of the time and a squad leader the rest. May be Mason right front(?)
Johnson center, Dan McFadden on the right, King just past McFadden's shoulder.
Ken York at left holding flag. Also possibly a man name Mickey.
