Another term is "GREEN AMPHIBIAN MONSTERS". Marines are that of Amphibians as Navy is that of Sailors. Since Navy and Marines ride together, they use the same terminology such as AYE AYE SIR and PORT/STARBOARD, and BULKHEAD, BOW/STERN FORWARD/AFT, QUARTERDECK, MAST
, all they talk about in boat terminology. The Marines travel on Naval vessels, because that is the primary mission of U.S. Marines. To engage in operations and missions where Naval task forces are present.
As far as working for MSC as a contractor on military equipment
, not really passengers. We were considered SHIPS CREW. We are not there on pleasure cruises but rather working in our professions. (In charge of military hardware
on the vessel.) Just so happened to be in a shipboard enviroment due to nature of prepositioned hardware
....we carried DOD ID cards could shop at the PX and base on Guam
or wherever we went were there were bases.
To the Navy, we took up berthing space, and used up their water
supply and flooded the galley's. We were on there for a short stint versus they that were actually attached to the vessel as permanent crew. We eventually would splash on shore with our AAV's and be gone. They were the sailors.
Merchant Seaman I shipped with were part of the SIU, or Seafarer's International Union. They had "Z" cards and they were documented by the Coast Guard. They had the deck
hands, the engine
compartments and the cooks. Of course, then the mates and officers. All had to do with the ship somehow. The ABS even steered the ship on watches.
