I note nothing mentioned about sexually transmitted diseases, but those in themselves took tally for many a soldier abroad. I saw close up a Doctors kit from those times, and blimey not something you would want to use, without a general aneasthetic.
Reminds me as a young soldier being played the Syphillis video from the U.S. on men returning from Vietnam, whilst we were in Malaya, no comparison I know, but it was meant to shock us, and it certainly had an effect.
I went straight down to Jahore Bahru that night with a bunch of mates and had a bloody good massage!
