Coasties are actually enlisted for their prep year. They are issued uniforms, "trops" being last thing as they must earn them. The 2.5 to 3 weeks they are at the Academy prior to MMI or GMC is basically CGA Swab Summer condensed to 3 weeks. So yes, they have been worked over already and do look pretty good when they show up. DS was Coastie at MMI this past year.
