Hey peanut butter is the bestI would tend to agree. However, most of the photos I've seen from Vietnam show little foliage use by Army Infantry. Not saying they didn't use it. I've also noted photos where the soldiers used burlap strips to break up the shape of their steel pots.
As for the topic at hand, I can offer a few that I have archived from photographs:
"Death from Above"
"The Herd" (Referance to the 173rd AB nickname)
"Pot is better than peanut butter"
"Make love, Not War"
"This Side Toward Enemy"
"Where is Lee Harvey Oswald now that we need him?"
