actually, kerry did serve two "tours"
from his records that he did release
jun 8 '66 - kerry reports to USS Gridley - "serves in serveral capacities"
what every body doesn't seem to talk about is what the uss gridley is - a ship in the military sea transport services in the atlantic - sounds like a supply ship - a really dangerous job, heh?
in feb 9 '68 - USS Gridley gets orders to deploy to west pac assignment - during this assignment, it gets sent to vietnam, i think , which is his basis for his first tour of duty in vietnam.
somewhere around here, he hears that the uss gridley will be decommisioned for retrofit on return to the U.S, which meant that kerry could have been reassigned anywhere.so
on feb 10 ’68 – kerry request for transfer to vietnam as swift boat officer “request for swift boat duty” (thinking that it was a cush job?). it isn't clear where or when he gets the idea to try to get three purple hearts to get out of serving,
