Indeed you are correct.
I wasn't there but his Marine buddy whose name he found on 'the wall' and ostentatiously wept next to for a photo op was.
What was that Marines name?
Mr Rose served in Hong Kong in the 1960's. He would definitely have been issued a yellow UN Health Card or a "Carte Jaune"

There is a record of Mr Rose's Carte Jaune.
There are specific innoculations that are discrete for Vietnam that were not deemed necessary for Hong Kong service.
I wonder if he can tell us what they were and when he received them.
'Carte Jaune's' are very difficult to purchase on ebay and besides the duplicate records are held by the WHO in Zurich.
Military or otherwise, nobody got into South Vietnam, without a valid passport, visa and Carte Jaune. You can ask anyone "who was there, man!"
John Del Vecchio claims that only 1 in 10 serving in Vietnam were involved in combat. The rest were bureaucrats that made sure people's papers were in order, the mail got delivered, reports and returns were completed and submitted in time. This is what the 'mi chang' with PRU's did,
Phoenix was classified then. It isn't now.
The 'Greek letter' projects were, compared to Phoenix, super dooper double top secret at the time for political reasons. But even DELTA, GAMMA, SIGMA and OMEGA are all de-classified these days. There was nothing particularly special about Phoenix.
An enterprising journalist should be able to easily establish the facts.
I am afraid I must disagree with you in regard to passports and visas.
In the two tours I spent there, I never had a passport or visa at any time, in fact, did not need a passport for any military travel whilst I was in.
I did indeed have a health card and recall it was designated HQ8.
I did not acquire a passport until roughly 1978, and that was after I left the green machine.
