>>And what is a "A SEA SERVICE DEPLOYMENT RIBBON?? "
In a nutshell it's for duty with Fleet Marine Force commands, for 12 months accumulated sea duty, or for at least one deployment of 90 consecutive days.
There's also a special ribbon/medal for having your picture taken with your girlfriend holding a stupid sign mocking your command structure. I think it's got a rainbow with a golden condom at the end of it.
"deployment of 90 consecutive days. "
