There were a  bunch (almost fifty) Army medical  folks  stationed in
Bangkok at a SEATO medical research facility. They were from Walter Reed in DC,
doing medical research all over Thailand, VN, and other places where we
had no presence.  I went down there several times to scrounge medical supplies
with a 3/4 ton truck, as our supply chain in Korat at the time was pretty
low in the pecking order.
