Hi Rajan, You don't say how old you are, so I'm guessing, but that must have been pretty soon after Goa's annexation from Portugal. I know there was some fighting during the annexation. I've always stayed away from combat pictures, but in the background of these there always was a tenseness. The Vietcong used Can Tho as an R&R center, so they kept distractions to a minimum, but the threat always was there.
Here's one I'm quite sure I've posted before, but it belongs with the others.
