6) If you witness someone calling the U.S. Coast Guard nonmilitary, inform them of their mistake... and kick their ass.
Last summer a real cute Coastie moved in beside me. I jokingly said that the neighborhood had a lot of military and a few Coast Guard.
She bristled.
I calmed her down when I mentioned that moving from the Department of Transportation to the Department of Homeland Security almost brought them back into the fold. I still consider them more as cops than military, except when deployed in war.
