tutelary

tutelary - adj - having the guardianship or charge of protecting a person or thing; guardian; protecting

I always thought it would be cool to be in the SecretService and protect the President or other foreign dignitaries. I just never had that particular opportunity arise. However, during Operation Iraqi Freedom, I did serve on a protective service detail for the admiral in charge of the port the rest of my unit was protecting. It was, from my perspective, quite an enjoyable experience.
