I Chuck Alexander was an SM2 aboard the USS Galveston CLG3 in 1964. We pull into Subic Bay,PI. For a 3 day R&R and when we were getting ready to pull out a group of Sailors along with a small metal shack came aboard. We were at sea for 30 days, pulled Back into Subic Bay and these folks got off and took their trailer with them and we got Underway for another 60 days before pulling back into Subic Bay for 3 days. I was very courious About those sailors that only were at sea for 30 days. I started asking around and was told They were CT’s but no one knew what they were doing with their little trailer. I went to the Personal office and was told CT’s did very little sea duty WOW I was on my 6th year of sea duty. I put in a request to change to CT , the next thing I knew I was on my way to Pensacola, Fl. As they say the rest is history and thank goodness I converted as the rest of my 22 years Was great.
